Continued from preceding page
Power supply pin (output and regulator
circuit power supply). Connect to
ground via capacitor to prevent noise.
When using the IC with a single 5V
source, short this pin to the V
REG pin.
Hall inputs for various phases
Logic "High" indicates VIN+>VIN-.
FG comparator input
Pin 35: Non-inverted input
Pin 36: Inverted input
Reference signal oscillator for motor
lock protection circuit, clock interrup-
tion error protection circuit etc.
Connect to ground via capacitor.
Connect directly to ground if protection
circuit is not to be used.
