The 1ED44175N01B is a low-voltage, power IGBT, non-inverting gate driver. Proprietary latch-up 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 1ED44175N01B has OCP pin for over current protection sense and a FAULT status output (when activivated, EN/FLT pin is internally pulled down). The EN/FLT needs to be externally pulled up to provide normal operation, pulling EN/FLT low disable the driver. Internal circuitry on VCC pin provides an under voltage lockout protection that holds output low until Vcc supply voltage is within operating range.
