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.  
12  
From start to 5 Hz: When driven by square wave (120° turn-on) f = f /(2 × 32 × 6)  
osc  
= 4 MHz, approx. 5 Hz

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

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.

4. Correcting the lead angle  
The lead angle can be corrected in the turn-on signal range from 0 to 58° in relation to the induced  
voltage.

0 V = 0°

5. Setting the carrier frequency  
This function sets the triangular wave cycle (carrier cycle) necessary for generating the PWM signal.  
(The triangular wave is used for forcibly turning on the lower transistor when the motor is driven by  
square wave.)  
Carrier cycle = f /252 (Hz)

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.  
*: When the REV pin is set to LOW, and the Hall signal is higher than 5 Hz, sine-wave drive mode is turned  
on.  
7. Protecting input pin  
(1) Overcurrent protection (Pin I

)
When the DC-link-current exceeds the internal reference voltage, gate block protection is performed.  
Overcurrent protection is released for each carrier frequency.  
Reference voltage = 0.5 V (typ.)  
(2) Positional signal abnormality protection  
Output is turned off when the positional signal is HHH or LLL; otherwise, it is restarted.  
(3) Monitor protection for V low supply voltage

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.  
Note 4: This part is used to set the value for overcurrent detection. I

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

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

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  
150˚C. The maximum heat is 260˚C, to be applied within 10 seconds and as far as the lead stopper.

Notes on contents  
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  
rights.  
6. Test Circuits  
Components in test circuits are used only to obtain and confirm device characteristics. These components and  
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.
