Half Bridge Driver is a unidirectional motor driver circuit that uses two MOSFETs to circulate the input power through the motor via a control logic such as PWM. In this configuration, the high-side MOSFET is the driver that switches on and off the input power and the low-side MOSFET is the flywheel MOSFET that lets the current circulate whenever the high-side MOSFET is turned off.
