... TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic 1 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 ...

... Description of Multi-Protective Operation The TA8050F has functions for protection from overvoltage (V functions protect the IC (and the motor load in some cases) from deterioration or destruction due to power-related overstress. The three functions work independently. Each function is explained below Overvoltage protection (V ● Basic operation When the voltage supplied to the V the input signals ...
