Motor driver ICs
Reversible motor driver
BA6218
The BA6218 reversible-motor driver supplies an output current of 0.7A (maximum). Two logic inputs allow four output
modes: forward, reverse, idling, and braking. The logic section and power section have separate ground pins. By con-
necting an electronic governer, the IC can be used for controlling reversible, variable-speed motors.
