High Power H Bridge Ic. Rohm h bridge ics are specified to handle esd volt ages as high as 4 kv. 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.
Rohm sh bridge driver ics offer a simple solution for high efficiency pulse width modulation pwm motor speed control using either the built in vref variable function to change the duty pulse or direct pwm control via ttl logic level input from an mcu. About h bridge i don t want ready made ic to drive the n mos i want to experiment by myself like you did i want to drive bipolar stepper motor with all possible options like chopper and microstep but without ready made ic and with variable powerfull power supply till 50v to test various stepper motors i want use only p n mos as driver. Infineon offers dedicated devices for automotive applications as the tle9201sg which is a 6a h bridge qualified according to aec q100 and fulfills high quality and reliability standards for automotive applications like exhaust gas recirculation egr idle speed control or water pumps.
Diagram of the hip4080a ic is shown in figure 1.
Two logic inputs control the h bridge driver which consists of four n channel mosfets that drive motors bi directionally with up to 10 a peak current. Rohm h bridge ics are specified to handle esd volt ages as high as 4 kv. Diagram of the hip4080a ic is shown in figure 1. Full h bridge circuits capable of a few amps can be purchased in convenient ic packages see pwm and h bridge chips.
