9.
5-V-Internal Regulator
External input voltage at VCC = 15 V (typ.) is dropped to 5 V so as to be used as the reference voltage for
the internal circuits of the IC. The reference voltage is generated at the Vrefout pin, to which a pull-up
resistor can be connected (5 V, 5 mA (max)). A capacitor must also be connected for oscillation protection.
10. Setting Carrier Frequency
Sets triangular-wave frequency (carrier frequency) required to generate the PWM signal at the drive
output.
Carrier frequency
= fosc/252 (Hz)
fosc = Reference clock (CR oscillation frequency)
Example) When fosc = 5 MHz, fc = 19.8 kHz
11. Dead Time Function (high/low-side transistor output off-time)
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.)
TOFF = 9/fosc
When fosc = 5 MHz, TOFF = 1.8 s
12. Outputting the Reverse Rotation Detection Signal
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.
