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
