1ED44175N01B Single-channel low-side IGBT gate driver IC with over-current protection Features Potential applications Over-current detection with negative voltage input Digitally controlled PFC -0.246 V over-current threshold with accurate 5% tolerance Home appliances Single pin for fault output and enable Air conditioner Programmable fault clear time Industrial applications Under voltage lockout for IGBTs General purpose low-side gate driver for single- single-ended topologies CMOS Schmitt-triggered inputs 3.3 V, 5 V and 15 V input logic compatible 25 V V voltage supply support (max) CC Output in phase with input -10 Vdc negative Input capability of OCP pin 3 kV ESD HBM RoHS compliant Description 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 V pin provides an under CC voltage lockout protection that holds output low until Vcc supply voltage is within operating range.
