Working Principles

The TPIC6259N is based on the H-Bridge configuration, which allows bidirectional control of DC motors. By controlling the input signals (Input A1, Input A2, Input B1, Input B2), the motor's speed and direction can be adjusted. The enable pins (Enable A and Enable B) are used to activate or deactivate the corresponding motor channel. When enabled, the outputs (Output A1, Output A2, Output B1, Output B2) provide the necessary current to drive the motor.
