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 connecting an electronic governer, the IC can be used for controlling reversible, variable-speed motors. Features 1) Built-in surge absorbing diodes. 2) Small standby supply current. 3) Wide range of operating voltage. (4.515V) 4) Interfaces with TTL devices.
