H Bridge Driver Circuit. An h bridge is a simple circuit that lets you control a dc motor to go backward or forward. To build an h bridge the only option is not to use an ic chip for an h bridge.
The h bridge driver ic is the chip between the arduino and the mosfet outputs. In the most simplistic terms an h bridge circuit can switch the polarity of the attached load. An h bridge is a simple circuit that lets you control a dc motor to go backward or forward.
The h bridge driver ic is the chip between the arduino and the mosfet outputs.
This circuit is called h bridge because the mosfets form the two vertical strokes and the motor forms the horizontal stroke of the alphabet h. The most common use of an h bridge is to drive a dc motor allowing directional control. In particular a bipolar stepper motor is almost invariably driven by a motor controller. There are various h bridge designs and some use discrete components consisting of mosfets while other designs utilize a dedicated integrated chip ic h bridge.
