TA8050F
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
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.
