Power supply pin for all voltage
except output transistors, source
predrive, and low current control
amplifier.
Reverse detector pin
Forward rotation: High
Reverse rotation: Low
1 Hall element waveform Schmitt
comparator composite output
U phase Hall element input and
reverse detector U phase Schmitt
comparator input pin.
Logic High indicates UIN1 > UIN2.
V phase Hall element input and
reverse detector V phase Schmitt
comparator input pin.
Logic High indicates VIN1 > VIN2.
W phase Hall element input and
reverse detector W phase Schmitt
comparator input pin.
Logic High indicates WIN1 > WIN2.
Hall element lower side bias voltage
supply pin.
When this pin is at 0.7V or lower, or
when it is open, all circuits are
inactive.
When driving motor, set this pin to
2V or higher.
