1ED44173N01B Single-channel low-side MOSFET gate driver IC with fast OCP Features Potential applications Over-current detection (OCP) 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 MOSFETs General purpose low-side gate driver for single- CMOS Schmitt-triggered inputs single-ended topologies 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 V negative Input capability of OCP pin DC 3 kV ESD HBM RoHS compliant Description The 1ED44173N01B is a low-voltage, power MOSFET non-inverting gate driver. 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 1ED44173N01B has OCP pin for over current protection sense and a FAULT status output (Once it is active, EN/FLT pin is internally pulled down). The EN/FLT needs to be outside pulled up to provide normal operation, pulling EN/FLT low disable the driver. Internal circuitry on V pin provides an under voltage lockout protection CC that holds output low until V supply voltage is within operating range.
