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.

2) Wide range of operating voltage. (4.5  15V)

3) Interfaces with TTL devices.

4) Built-in thermal shutdown circuit.

Motor driver ICs BA6418N (9) ASO Make sure that the output current and supply voltage do not exceed the ASO values. (10) Precautions for input mode switching To ensure reliability, it is recommended that the mode switching for the motor pass once through the open mode. (11) In-rush current There are no circuits built into these ICs that prevent inrush currents. Therefore, it is recommended to place a current limiting resistor or other physical countermeasure.
