Constant current control amplifier
voltage supply pin
Power supply pin for all circuits
except output transistors, source
predriver, 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.
Control loop frequency compensa-
tor pin. Connecting a capacitor
between this pin and GND prevents
closed loop oscillation in current
limiting circuitry.
