Functional Description
1. Basic
operation
The motor is driven by the square-wave turn-on signal based on a positional signal. When the positional
signal reaches number of rotations f
= 5 Hz or higher, the rotor position is estimated according to the
positional signal and a modulation wave is generated. The modulation wave and the triangular wave are
compared; then the sine-wave PWM signal is generated and the motor is driven.
From start to 5 Hz: When driven by square wave (120 turn-on) f
= f
osc
/(2
12
32 6)
5 Hz~: When driven by sine-wave PWM (180 turn-on); when f
osc
= 4 MHz, approx. 5 Hz
2. V
e
voltage command input and bootstrap power supply
(1)
Voltage command input: When V
e
<
= 1.0 V
U, V and W signals are stopped to protect IGBTs
(2)
Voltage command input: When 1.0 V
< V
e
<
= 2.1 V
The low-side IGBTs are turned on at a fixed frequency (carrier frequency) (duty cycle: 8%).
(3)
Voltage command input: When V
e
> 2.1 V
The U, V and W signals are driven out during sine wave drive.
The low-side IGBTs are forced to on at fixed frequency (carrier frequency) during square-wave drive
(duty cycle: 8%).
Note 1: At startup, the low-side IGBTs must be turned on for a fixed period at 1.0 V
<
V
e
<
=
2.1 V to charge the
high-side IGBT power supply.
3. Dead time function: upper/lower transistor output off-time
When the motor is driven by sine-wave PWM, dead time is digitally generated inside the IC to prevent
short circuit caused by the simultaneously turning on of upper and lower external power devices. When a
square wave is generated in full-duty cycle mode, the dead time function is turned on to prevent a short
circuit.

voltage.

square wave.)

6. Outputting the reverse rotation detection signal
This function detects the motor rotation direction every electrical angle of 360. This function judges
whether the actual direction of a rotating motor coincides with that of the internal reference voltage.

CW or CCW of the motor is determined by the direction of the Hall signal, which is specified in the timing
chart on page 9.

on.

Note 1: For carrier frequency and dead time, connect a 4.19 MHz ceramic resonator.
Note 2: These parts are used as a low-pass filter for noise absorption. Test to confirm noise filtering, then set the
filter time-constant.
Note 3: This part is used as a capacitor for power supply stability. Adjust the part to the application environment as
required. When mounting, place it as close as possible to the base of the leads of this product to improve
the noise elimination.

(V

Note 5: The required bootstrap capacitance value varies according to the motor drive conditions. The voltage stress
for the capacitor is the value of V
CC15
.
Other Precautions
A short circuit between the outputs, or between output and supply or ground may damage the device. Peripheral
parts may also be damaged by overvoltage and overcurrent. Design the output lines, V
CC
and GND lines so that
short circuits do not occur.
Also be careful not to insert the IC in the wrong direction because this could destroy the IC.
In turning on the power, first supply Vcc15 and confirm its stability; then apply Vcc7 and the driving input signal.
Vcc15 and VB may be turned on in either order. In turning off the power, take care not to cut off the VB line by
relay while the motor is spinning. Doing so may cause the IC to break down by cutting the current-producing route
for VB.
The TB6581H/HG is sensitive to electrostatic discharge. Handle with care.
The product should be mounted by the solder-flow method. The preheating time is from 60 to 120 seconds at
150C. The maximum heat is 260C, to be applied within 10 seconds and as far as the lead stopper.

1. Block Diagrams
Some functional blocks, circuits, or constants may be omitted or simplified in the block diagram for explanatory
purposes.
2. Equivalent Circuits
The equivalent circuit diagrams may be simplified or some parts of them may be omitted for explanatory
purposes.
3. Timing Charts
Timing charts may be simplified for explanatory purposes.
4. Maximum Ratings
The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not
be exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be
irreparably altered, in which case the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in
other equipment. Applications using the device should be designed so that no maximum rating will ever be
exceeded under any operating conditions.
Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set
forth in this document.
5. Application Circuits
The application circuits shown in this document are provided for reference purposes only. Thorough evaluation
is required in the mass production design phase.
In furnishing these examples of application circuits, Toshiba does not grant the use of any industrial property

circuits are not guaranteed to prevent malfunction or failure in application equipment.
Handling of the IC
Ensure that the product is installed correctly to prevent breakdown, damage and/or degradation in the product
or equipment.
Over-current protection and heat protection circuits
These protection functions are intended only as a temporary means of preventing output short circuits or other
abnormal conditions and are not guaranteed to prevent damage to the IC.
If the guaranteed operating ranges of this product are exceeded, these protection features may not operate
and some output short circuits may result in the IC being damaged.
The over-current protection feature is intended to protect the IC from temporary short circuits only.
Short circuits persisting over long periods may cause excessive stress and damage the IC. Systems should
be configured so that any over-current condition will be eliminated as soon as possible.
Counter-electromotive force
When the motor reverses or stops, the effect of counter-electromotive force may cause the current to flow to the
power source.
If the power supply is not equipped with sink capability, the power and output pins may exceed the maximum
rating.
The counter-electromotive force of the motor will vary depending on the conditions of use and the features of
the motor. Therefore make sure there will be no damage to or operational problem in the IC, and no damage to
or operational errors in peripheral circuits caused by counter-electromotive force.
