Working Principles

The SN75462D operates based on the H-bridge configuration. It consists of four power transistors that form two pairs of complementary switches. By controlling the input signals and enable pins, the IC can selectively turn on/off the transistors, allowing current flow in either direction through the motor windings. This enables bidirectional motor control.
