IR2112 High and Low Side Gate Driver IC (MOSFET and IGBT Driver)

The IR2112 is a high voltage, high speed gate driver IC designed to control high side and low side power MOSFETs or IGBTs in power switching circuits. It features separate high side and low side control inputs and corresponding gate drive outputs, providing flexibility for half bridge and other switching configurations. Its floating high side driver supports bootstrap operation for applications where the high side switch operates above circuit ground.
