AUIR3240STR Infineon

The AUIR3240STR with Gate Drivers Low Quies. Curr Gate Driver 75V 50A Auto manufactured by Infineon is a double-channel intelligent power module (IPM) designed to drive IGBTs and MOSFETs in inverter-based applications. It consists of two power and return pins, a low quiescent current gate driver, a fault flag output pin, an opto-isolator, and a shielded package. The low quiescent current allows for a low operating power consumption, which is beneficial for the efficiency of the inverter system. The two power and return pins are provided to directly connect the module to the open MOSFET or IGBT gate, eliminating the need of external controller circuits. The opto-isolator bit ensures an extended interference immunity of the driver, and the shielded package allows for a higher immunity to electromagnetic disturbances. The fault flag output pin allows it to quickly detect short circuits or overvoltages, helping to protect the system from damage.
