TA8053H
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8053H
3A DC MOTOR DRIVER WITH DIAGNOSIS
The TA8053H is a bidirectional DC motor driver with a current
capacity of 3A. Inputs DI1 and DI2 are combined to select one of
forward, reverse, stop, and brake modes.
The inputs are TTL−compatible, and separate power supplies are
provided for the logic and output sections. The IC also
incorporates various protective functions as well as a
self-diagnostic function for diagnostic output
