High Voltage H Bridge Circuit. Component count extras. 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 some drivers also have special circuitry to prevent shoot through when 2 fets create a direct short circuit to ground destroying the fets i.
1 n channel opto isolated mosfet switching circuit using irf630. An h bridge is an electronic circuit that switches the polarity of a voltage applied to a load. An h bridge is a simple circuit that lets you control a dc motor to go backward or forward.

The switching elements q1 q4 are usually bi polar or fet transistors in some high voltage applications igbts.

Note first the 5 2k resistor and 12 volt zener diode.
