Mosfet H Bridge Motor 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. The drv8874 q1 is an integrated motor driver with n channel h bridge charge pump current sensing and proportional output current regulation and protection circuitry.
There is no problem with the high input capacitance of the irfp150 mosfets. In this article video i have introduced a complete h bridge dc motor driver using four ir3205 power mosfets and two ir2104 mosfet drivers. The h bridge driver ic is the chip between the arduino and the mosfet outputs.

Translate the input voltages to suitable levels to drive. The h bridge driver ic is the chip between the arduino and the mosfet outputs. 10 illustrates the use of a motor power switch to turn off a generic h bridge circuit. It is the simple and elegant solution to all motor driving problems.
