TA8050F

1.5 A DC Motor Driver with Brake Function

The TA8050F is a 1.5 A motor driver which directly drives a

bidirectional DC motor. Inputs DI1 and DI2 are combined to

select one of forward, reverse, stop, and brake modes. Since the

inputs are TTL-compatible, this IC can be controlled directly from

a CPU or other control system. The IC also has various protective

functions.
