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 assumed 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
5 Hz~: When driven by sine-wave PWM (180° turn-on) When f
2. Function to stabilize bootstrap voltage
(1) When voltage instruction is input at V
Turns on the lower transistor at regular (carrier) cycle. (On duty is approx. 8%)
(2) When voltage instruction is input at V
During sine-wave drive, outputs drive signal as it is.
During square-wave drive, forcibly turns on the lower transistor at regular (carrier) cycle.

3. Dead time function: upper/lower transistor output off-time
When driving the motor by sine-wave PWM, to prevent a short circuit caused by simultaneously turning
on upper and lower external power devices, digitally generates dead time in the IC.

4. Correcting 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 to 5 V divided by 32)
0 V = 0°
5 V = 58° (when more than 5 V is input, 58°)
5. Setting carrier frequency
Sets triangular wave cycle (carrier cycle) necessary for generating PWM signal.
(The triangular wave is used for forcibly turning on the lower transistor when driving the motor by
square wave.)

6. Switching the output of turn-on signal
Switches the output of turn-on signal between high and low.

High = active high

7. Outputting reverse rotation detection signal
Detects motor rotation direction every electrical angle of 360°. (The output is high immediately after
reset)

8. Protecting input pin
1. Overcurrent protection (Pin Idc)
When the DC-link-current exceeds the internal reference voltage, performs gate block protection.
Overcurrent protection is released for each carrier frequency.
Reference voltage = 0.5 V (typ.)
2. Gate block protection (Pin RES)
When the input signal level is Low, turns off the output; when High, restarts the output.
Detects abnormality externally and inputs the signal to the pin RES.

(When RES = Low, bootstrap capacitor charging stops.)
3. Internal protection
· Positional signal abnormality protection
When the positional signal is HHH or LLL, turns off the output; otherwise, restarts the output.
· Low power supply voltage protection (V
When power supply is on/off, prevents damage caused by short-circuiting power device by
keeping the turn-on signal output at high impedance outside the operating voltage range.

The modulation waveform is generated using Hall signals. Then, the modulation waveform is compared
with the triangular wave and a sine-wave PWM signal is generated.
The time (electrical angle: 60°) from the rising (or falling) edges of the three Hall signals to the next
rising (or rising) edges are counted. The counted time is used as the data for the next 60° phase of the
modulation waveform.
There are 32 items of data for the 60° phase of the modulation waveform. The time width of one data
item is 1/32 of the time width of the 60° phase of the previous modulation waveform. The modulation
waveform moves forward by the width.

The phases are matched between every rising edge of the HU signal and the modulation waveform. The
modulation waveform is reset in sync with the rising edge of the HU signal at every electrical angle of 360°.
Thus, when the Hall signal rising edge is mispositioned or at acceleration/deceleration, the modulation
waveform is non-consecutive at every reset.

To stabilize the bootstrap voltage, the lower outputs (X, Y, and Z) are always turned on at the carrier cycle
even during off time. At that time, the upper outputs (U, V, and W) are assigned dead time and turned off
