Infineon Technologies 1ED44173N01B Non-Inverting Gate Driver

Infineon 1ED44173N01B Non-Inverting Gate Driver is a low-voltage, power MOSFET non-inverting gate driver with overcurrent protection (OCP). Proprietary latch-immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output. The output driver features a current buffer stage. The Infineon 1ED44173N01B has an OCP pin for over-current protection sense and a FAULT status output (once it is active, the EN/FLT pin is internally pulled down). The EN/FLT needs to be outside and pulled up to provide normal operation, pulling EN/FLT low disable the driver. Internal circuitry on the VCC pin provides under-voltage lockout protection that holds output low until the VCC supply voltage is within the operating range.
