FUNCTIONAL DESCRIPTION

Supply voltage

The UBA2032 is powered by a supply voltage applied to
pin HV, for instance the supply voltage of the full bridge.
The IC generates its own low supply voltage for the
internal circuitry. Therefore an additional low voltage
supply is not required. A capacitor has to be connected to
pin V

to obtain a ripple-free internal supply voltage. The

circuit can also be powered by a low voltage supply directly
applied to pin V

. In this case pin HV should be

connected to pin V

or SGND.

Start-up

With an increasing supply voltage the IC enters the
start-up state; the higher power transistors are kept off and
the lower power transistors are switched on. During the
start-up state the bootstrap capacitors are charged and the
bridge output current is zero. The start-up state is defined
until V

= V

DD(UVLO)

, where UVLO stands for Under

Voltage Lock-out. The state of the outputs during the
start-up phase is overruled by the bridge disable function.

Release of the power drive

At the moment the supply voltage on pin V

or HV

exceeds the level of release power drive the output voltage
of the bridge depends on the control signal on pin EXTDR
see Table 1. The bridge position after start-up, disable, or
delayed start-up (via pin SU) depends on the status of the
pins DD and EXTDR. If pin DD = LOW (divider enabled)
the bridge will start in the pre-defined position pin GLR
and pin GHL = HIGH and pin GLL and pin GHR = LOW.
If pin DD = HIGH (divider disabled) the bridge position will
depend on the status of pin EXTDR.

If the supply voltage on pin V

or HV decreases and

drops below the reset level of power drive the IC enters the
start-up state again.

Oscillation

At the point where the supply voltage on pin HV crosses
the level of release power drive, the bridge begins
commutating between the following two defined states:

Higher left and lower right MOSFETs on,
higher right and lower left MOSFETs off

Higher left and lower right MOSFETs off,
higher right and lower left MOSFETs on.

Preliminary specification

UBA2032

The oscillation can take place in three different modes:

Internal oscillator mode.

In this mode the bridge commutating frequency is
determined by the values of an external resistor (R

osc

)

and capacitor (C

osc

). In this mode pin EXTDR must be

connected to pin +LVS. To realize an accurate 50% duty
factor, the internal divider should be used. The internal
divider is enabled by connecting pin DD to SGND. Due
to the presence of the divider the bridge frequency
is half the oscillator frequency. The commutation of the
bridge will take place at the falling edge of the signal on
pin RC. To minimize the current consumption
pins +LVS,

LVS and EXTDR can be connected

together to either pin SGND or V

. In this way the

current source in the logic voltage supply circuit is shut
off.

External oscillator mode without the internal divider.

In the external oscillator mode the external source is
connected to pin EXTDR and pin RC is short-circuited to
pin SGND to disable the internal oscillator. If the internal
divider is disabled (DD = V

) the duty factor of the

bridge output signal is determined by the external
oscillator signal and the bridge frequency equals the
external oscillator frequency.

External oscillator mode with the internal divider.

The external oscillator mode can also be used with the
internal divider function enabled (RC = DD = SGND).
Due to the presence of the divider the bridge frequency
is half the external oscillator frequency. The
commutation of the bridge is triggered by the falling
edge of the EXTDR signal with respect to V

LVS

If the supply voltage on pin V

or HV drops below the

reset level of power drive, the UBA2032 re-enters the
start-up phase. The design equation for the bridge

oscillator frequency is:

Non-overlap time

The non-overlap time is the time between turning off the
conducting pair of MOSFETs and turning on the next pair.
The non-overlap time is realized by means of an adaptive
non-overlap circuit. With an adaptive non-overlap, the
application determines the duration of the non-overlap and
makes the non-overlap time optimal for each frequency.
The non-overlap time is determined by the duration of the
falling slope of the relevant half bridge voltage (see Fig.4).
The occurrence of a slope is sensed internally. The
minimum non-overlap time is internally fixed.

Divider function

If pin DD = SGND then the divider function is
enabled/present. If the divider function is present there is
no direct relation between the position of the bridge output
and the status of pin EXTDR.

Start-up delay

Normally, the circuit starts oscillating as soon as pin V

HV reaches the level of release power drive. At this
moment the gate drive voltage is equal to the voltage on
pin V

for the low side transistors and V

0.6 V for the

high side transistors. If this voltage is too low for sufficient
drive of the MOSFETs the release of the power drive can
be delayed via pin SU. A simple RC filter (R between
pins V

and SU; C between pins SU and SGND) can be

used to make a delay, or a control signal from a processor
can be used.

Bridge disable

The bridge disable function can be used to switch off all the
MOSFETs as soon as the voltage on pin BD exceeds the
bridge disable voltage (1.29 V). The bridge disable
function overrules all the other states.

APPLICATION INFORMATION

Basic application

A basic full bridge configuration with an HID lamp is shown
in Fig.5. The bridge disable, the start-up delay and the
external drive functions are not used in this application.
The pins

LVS, +LVS, EXTDR and BD are short-circuited

to SGND. The internal oscillator is used and to realise a
50% duty cycle the internal divider function has to be used
by connecting pin DD to SGND. The IC is powered by the
high voltage supply. Because the internal oscillator is

used, the bridge commutating frequency is determined by
the values of R

osc

and C

osc

. The bridge starts oscillating

when the HV supply voltage exceeds the level of release
power drive (typically 12.5 V on pin HV). If the supply
voltage on pin HV drops below the reset level of power
drive (typically 10 V on pin HV), the UBA2032 enters the
start-up state.

Car headlight application

The life of an HID lamp depends of the rate of sodium
migration through the quartz wall of the lamp. To minimize
this, the lamp must operate negative with respect to the
system ground. Figure 5 shows a full bridge with an HID
lamp for a car headlight application, along with a control

circuit referenced to the system ground and with a bridge
voltage operating at high negative voltages with respect to
the system ground. Pin +LVS and HV can be connected to
the same supply as the control unit The output state of the
bridge is related to the position of pin EXTDR. See also the
timing diagram.

Additional application information

ATE RESISTORS

At ignition of an HID lamp, a large EMC spark occurs. This
can result in a large voltage transient or oscillation at the
gates of the full bridge MOSFETs (LL, LR, HR and HL).
When these gates are directly coupled to the gate drivers
(pins GHR, GLR, GHL and GLL), voltage overstress of the
driver outputs may occur. Therefore it is advised to add a
resistor with a minimum value of 100

in series with each

gate driver to isolate the gate driver outputs from the actual
power MOSFETs gate.

ATE CHARGE AND SUPPLY CURRENT AT HIGH FREQUENCY

USE

The total gate current needed to charge the gates of the
power MOSFETs equals:

Where:

gate

= gate current

bridge

= bridge frequency

gate

= gate charge.

This current is supplied via the internal low voltage supply
(V

). Since this current is limited to 11 mA (see table

"Characteristics", note 1), at higher frequencies and with
MOSFETs having a relative high gate charge, this
maximum V

supply current may not be sufficient

anymore. As a result the internal low voltage supply (V

)

and the gate drive voltage will drop resulting in an increase
of the on resistance (R

) of the full bridge MOSFETs. In

this case an auxiliary low voltage supply is necessary.

SOLDERING

Introduction to soldering surface mount packages

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

"Data Handbook IC26; Integrated Circuit Packages"

(document order number 9398 652 90011).

There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering can still be used for
certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.

Reflow soldering

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.

Typical reflow peak temperatures range from
215 to 250

C. The top-surface temperature of the

packages should preferable be kept below 220

C for

thick/large packages, and below 235

C for small/thin

packages.

Wave soldering

Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.

To overcome these problems the double-wave soldering
method was specifically developed.

If wave soldering is used the following conditions must be
observed for optimal results:

Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

For packages with leads on two sides and a pitch (e):

larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;

smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the
printed-circuit board.

The footprint must incorporate solder thieves at the
downstream end.

For packages with leads on four sides, the footprint must
be placed at a 45

angle to the transport direction of the

printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Typical dwell time is 4 seconds at 250

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Manual soldering

Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300

When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320

Suitability of surface mount IC packages for wave and reflow soldering methods

Notes

1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum

temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the

"Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods".

2. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder

cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,
the solder might be deposited on the heatsink surface.

3. If wave soldering is considered, then the package must be placed at a 45

angle to the solder wave direction.

The package footprint must incorporate solder thieves downstream and at the side corners.

4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;

it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is

definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
