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.)
Carrier cycle = fosc/252 (Hz)
fosc = Reference clock (crystal oscillation)
6. Switching the output of turn-on signal.
Switches the output of turn-on signal between high and low.
Pin OS:
High = active high
Low = active low
7. Outputting reverse rotation detection signal.
Detects motor rotation direction every electrical degrees of 360°. (The output is high
immediately after reset).
REV terminal increases with a 180° turn-on mode at the time of low.

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.
