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.
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.
Absolute maximum ratings (Ta = 25C)
Recommended operating conditions (Ta = 25C)
Electrical characteristics (unless otherwise noted, Ta = 25C, VCC = 9V)
