The IR21844SPBF is a Gate Driver HALF BRDG DRVR manufactured by Infineon. It is a 600V high voltage, 10 to 20V dual channel gate driver with a current rating of 1.4A. Its main function is to provide logic-level voltage adjustment to drive an external power MOSFET or IGBT bridge on a switching converter or similar application. It features a robust and durable design and has a low resistance RDS(ON). It also offers protection features such as circuit protection, over current protection, over temperature protection, and short circuit protection. Additionally, it is capable of providing fast switch turn OFF time, thus reducing power loss during operation. This gate driver can also be used to drive power switches in automotive applications such as ABS, ESP, and power steering systems.
