FCircuit operation
Input / output truth table
Forward / reverse control, forced stop, and rush current
absorption are controlled by the combination of F
R
(1)
When F
OUT1 to OUT2. When F
rent flows from OUT2 to OUT1 (refer to the truth table).
(2)
By setting R
supply to the motor is shut down and a brake is applied
by absorbing the motor counter-electromotive force.

(3)
When a high voltage (caused by such as a motor rever-
sal) is generated on OUT1 and OUT2, an internal
comparator detects the high voltage and turns on an in-
ternal circuit that absorbs rush currents.
(4)
The forward direction of the motor connected between
OUT1 and OUT2 corresponds to the current flow from
OUT1 to OUT2, and the reverse direction corresponds to
the current flow from OUT2 to OUT1. The output voltage
