H Bridge Mosfet Driver Circuit. Figure 10 mosfet h bridge motor control with motor power on off control. The main advantages of using an h bridge driver are high efficiency rotation direction change and braking the motor.
Driving mosfets after selecting acceptable mosfets for the designed h bridge the next critical step is to select a proper integrated circuit ic that will act as a buffer between the signal generator for high side low side control and the actual gates of the mosfets. H bridge motor driver circuit is used to control the speed and direction of a brushed dc motor. A low current digital signal controls a high current motor.
It is the simple and elegant solution to all motor driving problems.
This ic takes high low signals from the arduino and outputs the same boosted signal to drive the mosfet gates specifically its most important function is to increase the voltage to the high side fets above vcc battery input allowing for the use of all n mosfets. H bridge motor driver circuit is used to control the speed and direction of a brushed dc motor. I have used ir2210 mosfet gate driver circuit. The drive circuitry for an h bridge is basically the electronics that sits between the pwm and potentially other digital control inputs and the mosfet gates.
