An H-bridge motor driver is a power-integrated circuit that uses four switching elements arranged in an H configuration to drive a brushed DC motor bidirectionally from a single supply rail. It sits in the motor-control signal chain between a low-power MCU (logic-level PWM/direction commands) and a brushed DC or stepper motor, handling the high-current switching that the MCU cannot do directly.
