9. 5-V-Internal Regulator

11. Dead Time Function
12. Outputting the Reverse Rotation Detection Signal
External input voltage at V
the internal circuits of the IC. The reference voltage is generated at the V
resistor can be connected (5 V, 5 mA (max)). A capacitor must also be connected for oscillation protection.
Sets triangular-wave frequency (carrier frequency) required to generate the PWM signal at the drive
output.
When the motor is driven by sine-wave PWM, digitally generates the dead time in the IC to prevent a short
circuit caused by simultaneously turning on high/low-side external power devices. (When a square-wave is
generated in full duty cycle mode, the dead time function is also turned on to prevent a short circuit.)
T
When f
Detects motor rotation direction.
The detection is performed at every electrical angle of 360°. (The output immediately after reset is High.)
When the REV pin is Low, the 180° commutation drive mode (current frequency = 6 Hz or higher) is turned
on.
