Motor driver ICs Reversible motor driver BA6418N The BA6418N is a reversible-motor driver with a maximum output current of 0.7A. Two logic inputs allow four output modes: forward, reverse, stop (idling), and brake. Since logic and power sections have separate ground pins, the IC can drive speed-variable, reversible motors by connecting an electronic governor circuit. Features 1) Small standby circuit current. 3) Interfaces with TTL devices. 2) Wide range of operating voltage. (4.5 15V) 4) Built-in thermal shutdown circuit.
