DESCRIPTION

True digital audio amplifier (TDAA) is a new paradigm
in digital audio. The TDAA system currently consists of
the TAS5000 PCM-PWM modulator device + TAS5100
PWM power output device. This system accepts a serial
PCM digital audio stream and converts it to a 3.3-V
PWM audio stream (TAS5000). The TAS5100 device
then provides a large-signal PWM output. This digital
PWM signal is then demodulated providing power
output for driving loudspeakers. This patented
technology provides low-cost, high-quality,
high-efficient digital audio applicable to many audio
systems developed for the digital age. The TAS5100 is
a single-channel PWM power audio device. It contains
integrated gate drivers, four matched and electrically
isolated enhancement- mode N-channel power DMOS
transistors. Also, included are protection and
fault-reporting circuitry. This device is optimized for use
with the TAS5000 digital modulator.

SHUTDOWN

Device is in shutdown due to fault condition, normal mode = 1, shutdown = 0, when device is in

cleared by asserting the RESET signal. This output is open drain with internal pullup resistor.

VRFILT

A filter capacitor must be added between VRFILT and DVSS pins.

NOTE: The four PWM inputs: PWM_AP, PWM_AM, PWM_BP, and PWM_BM must always be connected to the TAS5000 output pins, and never

left floating. Floating PWM input pins will cause an illegal PWM input state signal to be asserted.

Dual pins: OUTPUTA, OUTPUTB, PVDDA1 and PVDDB1 must have both pins connected externally to the same point on the circuit board,
respectively. Both PVSS pins must also be connected together externally. These multiple pins are for the high current DMOS output
devices. Failure to connect all the multiple pins to the same respective node will result in excessive current flow in the internal bond wires
and can cause the device to fail. All electrical characteristics are specified and measured with all of the multiple pins connected to the same
node, respectively.

functional description

PWM H-bridge state control

The digital interface control signals consists of PWM_AP, PWM_AM, PWM_BP, and PWM_BM. These signals
are a complementary differential signal format for the A-side H-bridge and the B-side H-bridge.

bootstrapped gate drive

The TAS5100 includes 2 dedicated bootstrapped power supplies. A bootstrap capacitor is connected between
the individual bootstrap pin and the associated output as described in the application note SLAA117. For
example, a capacitor will be connected between the BOOTSTRAPA pin and OUTPUTA pin, and another
capacitor will be connected between the BOOTSTRAPB pin and the OUTPUTB pin. The bootstrap power
supply minimizes the number of high voltage power supply levels externally supplied to the system while
providing a low noise supply level for driving the high-side N-channel DMOS transistors. See application note
SLAA117 for details.

low-dropout voltage regulator

Two on-chip low-dropout voltage regulators (LDO) are provided to minimize the number of external power
supplies needed for the system. These voltage regulators are for internal circuits only and cannot be used for
external circuitry. Each LDO is dedicated to an H-bridge and its gate driver. An LDO output capacitor is
connected between the individual LDO output pin and the associated output return as described in the
application note SLAA117. For example, a capacitor will be connected between the LDROUTA pin and PVSS
pin, and another capacitor will be connected between the LDROUTB pin and PVSS pin.

high-current H-bridge output stage

The positive outputs of the H-bridge are the two OUTPUTA pins. The negative outputs of the H-bridge are the
two OUTPUTB pins. The logic for the input command to H-bridge outputs is described in the H-bridge output
mapping section below. When the TAS5100 is in the normal mode, as seen in the H-bridge output mapping
tables, the outputs are decoded from the inputs. However, the TAS5100 is immediately shut down if any of the
following error conditions occur: over-current, over-temperature, low regulator output voltage, or an illegal PWM
input state is applied. For these conditions, the outputs are set to the appropriate disabled state as specified
in the H-bridge output mapping section, and the SHUTDOWN pin is set low.

control/sense circuitry

The control/sense circuitry consists of the following 3.3-V logic level pins: PWDN, RESET, ERR0, ERR1, and
SHUTDOWN. The active-low PWDN input pin powers down all internal circuitry and forces the H-bridge outputs
to the Hi-Z state. When the PWDN pin is low, the open drain ERR0, ERR1, and SHUTDOWN pins are also
disabled so that their outputs can be pulled high. The active-low RESET input pin forces the H-bridge outputs
to the low-low state and resets the over-current shutdown latch. The PWDN pin overrides the RESET pin. The
ERR0, ERR1, and SHUTDOWN outputs indicate the following conditions in the TAS5100 as shown in the table
below. These three outputs are open-drain connections with internal pullup resistors so that wire-ORed
connections can be made by the user with other external control devices. The short circuit protect error condition
will latch the TAS5100 in this shutdown state and force the H-bridge outputs to the Hi-Z state until the device
is reset by means of the RESET pin. The illegal PWM input state, over-temperature, and low regulator voltage
error conditions will not latch the device in the shutdown condition. Instead the H-bridge outputs are forced to
the low-low state and the TAS5100 will return to normal operation as soon as the error condition ends. Loss of
clocking PWM signal is also considered an illegal PWM input state.

device operation

power sequences

system power-up/power-down sequencing

The recommended power-up/power-down sequence is shown in Figure 3. For proper operation the RESET
signal should be kept LOW when both DVDD and output power (PVDDA1, PVDDA2, PVDDB1, and PVDDB2)
are being applied. The RESET signal should remain LOW for at least 1 ms after output power is applied.

For most applications, it is recommended that pin 13 (PWDN) be connected directly to pin 6 (DVDD).

Figure 3. Power-Up/Power-Down Sequence

RESET function

The device is put into a reset condition when the (active low) RESET signal is asserted. While in the reset state,
the input H-bridge control signals consisting of PWM_AP, PWM_AM, PWM_BP, and PWM_BM are ignored, and
the H-bridge MOSFETs are placed in a state where OUTPUTA and OUTPUTB are both low. Asserting the
RESET signal low also causes the short circuit protection latch to be reset. The RESET signal is normally
connected to the VALID signal from the TAS5000.

reinitialization sequence

Proper initial conditions for this device include asserting the RESET signal until the reset operation has
completed (1 ms). Additionally, when using this device with the TAS5000 controller, this function can be
accomplished by asserting the reset pin on the TAS5000 during the reset sequence (see Figure 3).

audio application considerations

power supply decoupling

Power supply decoupling and layout optimization information should be obtained by following the detailed
information in the application note SLAA117.

optimal power transfer for H-bridge

The TAS5100 is a power H-bridge that is designed to deliver 30 W/rms into loads of 4

to 8

. Rather than

requiring the usual heatsink, the package is designed to deliver this wattage by careful layout as described in
the application note SLAA117. Careful attention must be given to the value of the high-voltage power supply
level for a given load resistance. See recommended operating conditions.

TAS5100

SLLS419B MARCH 2001 REVISED NOVEMBER 2001

www.ti.com

audio application considerations (continued)

reconstruction output filter

An output reconstruction filter is required between the H-bridge outputs and the loudspeaker load. This second
order low-pass filter passes the audio information to the loudspeaker, while filtering out the high frequency
out-of-band information contained in the H-bridge output PWM pulses. The values of the L and C components
selected are dependent on the loudspeaker load impedance. See application note SLAA117.

fault indicator usage

The TAS5100 is a self-protecting device that provides device fault reporting, including over-temperature protect,
under-voltage lockout (low-regulator voltage), and short circuit protection. The short circuit protection protects
against short circuits that may occur at the loudspeaker load when configured according to the application note
SLAA117. The TAS5100 is not recommended for driving loads less than 4

since the internal current limit

protection might be activated.

An under-voltage lockout signal occurs when an insufficient voltage level is present on the LDROUTA or
LDROUTB pins. During this condition gate drive levels are not sufficient for driving the power MOSFETs. Normal
operation is resumed when the minimum proper LDROUTA or LDROUTB level is obtained, and the low regulator
voltage protect signal is de-asserted. See the control/sense circuitry section for error and warning conditions.

A high temperature warning signal is asserted on pin ERR0 when the device temperature exceeds 110

typical.

If the internal device temperature exceeds 130

C typical, the over temperature protect signal is asserted and

the TAS5100 is shut down. The device will re-enable once the temperature drops to 110

C typical. See the

control/sense circuitry section for error and warning conditions.

Detection of an illegal PWM input state or the loss of a clocking PWM input signal will cause an illegal PWM input
state signal to be asserted on the ERR1and ERR0 pins and will set the SHUTDOWN pin to the low state.

One of the most influential components on the thermal performance of a package is board design. In order to take full advantage of the heat

dissipating abilities of the PowerPAD packages, a board must be used that acts similar to a heat sink and allows for the use of the exposed (and
solderable), deep downset pad. See Appendix A of the PowerPAD Thermally Enhanced Package application note, TI literature number SLMA002
and the Thermal Design of the PowerPad PCB Layout section of the System Design Considerations for True Digital Audio Power Amplifiers

THERMAL INFORMATION

The thermally enhanced DAP package is based on the 32-pin HTSSOP, but includes a thermal pad (see
Figure 4) to provide an effective thermal contact between the IC and the PWB.

Traditionally, surface mount and power have been mutually exclusive terms. A variety of scaled-down TO-220
type packages have leads formed as gull wings to make them applicable for surface-mount applications. These
packages, however, have two shortcomings: they do not address the very low profile requirements (<2 mm) of
many of today's advanced systems, and they do not offer a terminal-count high enough to accommodate
increasing integration. On the other hand, traditional low-power surface-mount packages require
power-dissipation derating that severely limits the usable range of many high-performance analog circuits.

The PowerPAD package (thermally enhanced HTSSOP) combines fine-pitch surface-mount technology with
thermal performance comparable to much larger power packages.

The PowerPAD package is designed to optimize the heat transfer to the PWB. Because of the very small size
and limited mass of a HTSSOP package, thermal enhancement is achieved by improving the thermal
conduction paths that remove heat from the component. The thermal pad is formed using a patented lead-frame
design and manufacturing technique to provide a direct connection to the heat-generating IC. When this pad
is soldered or otherwise thermally coupled to an external heat dissipater, high power dissipation in the ultrathin,
fine-pitch, surface-mount package can be reliably achieved. See dissipation derating table.
