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 = fosc/(212 x 32 x 6) 5 Hz~: When driven by sine-wave PWM (180 turn-on); when fosc = 4 MHz, approx. 5 Hz
2. Ve voltage command input and bootstrap power supply
(1) (2) (3) Voltage command input: When Ve < 1.0 V = U, V and W signals are stopped to protect IGBTs Voltage command input: When 1.0 V < Ve < 2.1 V = The low-side IGBTs are turned on at a fixed frequency (carrier frequency) (duty cycle: 8%). Voltage command input: When Ve > 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 < Ve < 2.1 V to charge the = high-side IGBT power supply.
PWM duty cycle
100%
(1) 0 to 1.0 V: Reset state (All outputs are off.) (2) Ve = 1.0 to 2.1 V: Startup operation (duty cycle of 8% for the low-side IGBTs) (3) Ve = 2.1 to 5.4 V: Running state (5.4 V or higher: PWM duty cycle = 100%)
(1) 1.0 V (2) 2.1 V (3) 5.4 V Ve
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.
Internal Counter 8/fosc
TOFF 1.9 s
TOFF values above are obtained when fosc = 4.19 MHz. fosc = reference clock (crystal oscillation)
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. Analog input from LA pin (0 V to 5 V divided by 32) 0 V = 0 5 V = 58 (when more than 5 V is input, 58)

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 = fosc/252 (Hz) fosc = reference clock (crystal oscillation)
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.
Actual Motor Rotating Direction CW (forward) CCW (reverse)
REV Pin HIGH LOW
Drive Mode Square waveform (120 turn-on mode) Sine-wave waveform (180 turn-on mode)
*: 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 Idc) 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.) Positional signal abnormality protection Output is turned off when the positional signal is HHH or LLL; otherwise, it is restarted. Monitor protection for VCC7/ VCC15 low supply voltage For power supply on/off outside the operating voltage range, the U, V and W drive outputs are turned off and the motor is stopped when there is a power supply fault. < VCC7>

Overheat protection The overheat protection circuit will operate and all IGBTs will be turned off if the chip temperature becomes abnormally high due to internal or external heat generation. TSD = 165C (typ.) TSDhys = 20C (typ.)
After the overheat protection circuit is turned on, the return temperature is 145C (typ.).

VCC15 power supply stability Bootstrap capacitor
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. Note 4: This part is used to set the value for overcurrent detection. Iout (max) = Vdc / R5 (Vdc = 0.5 V (typ.)) Note 5: The required bootstrap capacitance value varies according to the motor drive conditions. The voltage stress for the capacitor is the value of VCC15.
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, VCC 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.

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.
