Circuit Operation:
Forward and Reverse Control
By changing the direction of current flow between OUT1 and OUT2, the direction of motor rotation
is changes (Refer to the input
–
output truth table). When F
IN
is HIGH and R
IN
in LOW, current flows
from OUT1 to OUT2. When F
IN
is LOW and R
IN
is HIGH, current flolws from OUT2 to OUT1.
Forced Stop
Setting R
IN
and F
IN
both HIGH or both LOW puts both output pins at the same potential, shutting off
the supply current to the motor. When this happens, the motor generates a reverse current that pro-
duces a braking action.
Rush Current Absorption Circuit
The high voltage that appears on the OUT1 and the OUT2 (when the motor reverses) is sensed by
an internal comprator, which turns on an internal circuit that absorbs the rush current.
Drive Circuit
The drive circuit supplies the current necessary to drive a motor connected between the OUT1 and
OUT2 terminals. The forward direction of the motor is the direction of rotation when current flows from
OUT1 to OUT2 and the reverse direction is the direction of rotation when current flows from OUT2
to OUT1. The output voltage (V
OUT
) applied to the motor is given by the equation:
