None of the circuits operate if the
voltage on this pin is 0.7 V or less,
or if this pin is open.
When driving the motor, the
voltage on this pin must be 2 V or
more.

GND
Ground connection for all circuits
except the outputs.
Control loop frequency
characteristics compensation pin.
Connect a capacitor between this
pin and GND to stop closed loop
oscillation in the current control
system.
