H Bridge Driver Circuit. 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. You normally use it with a microcontroller such as an arduino to control motors.
These circuits are often used in robotics and other applications to allow dc motors to run forwards or backwards. An h bridge is a circuit that is used primarily to control motors. 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.
Simply put a dc motor spins when you connect it to a dc power source like a battery.
The circuit shown here is a typical four transistor h bridge. Simply put a dc motor spins when you connect it to a dc power source like a battery. The circuit given here is of a simple h bridge motor driver circuit using easily available components. In general an h bridge is a rather simple circuit containing four switching element with the load at the center in an h like configuration.
