Overview
TA8083P/F TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8083P,TA8083F DUAL DC MOTOR DRIVER The TA8083P、TA8083F contains two motor driver circuits with a current capacity of 0.
5A for directly driving bidirectional DC motors.
Inputs DI1 A / B and DI2 A / B 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.
In addition, the IC also has a low standby current function, a self-diagnostic function, and various protective functions.
FEATURES l 0.
