1ED44176N01F Single-channel low-side gate driver IC with over -current protection Features Potential applications Over-current detection with positive voltage input Digitally controlled PFC 0.5 V over-current threshold with accurate 5% Air conditioner tolerance Home appliances Single pin for fault output and enable Industrial applications Programmable fault clear time General purpose low-side gate driver for single-ended Under voltage lockout topologies CMOS Schmitt-triggered inputs 3.3 V, 5 V and 15 V input logic compatible Output in phase with input Separate logic and power ground 2 kV ESD HBM RoHS compliant Evaluation board available: EVAL-1ED44176N01F Description The 1ED44176N01F is a low-voltage, power MOSFET and IGBT 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 1ED44176N01F has OCP pin for over current protection sense and a FAULT status output (Once it is active, EN/FLT pin is internally pulled down.). There is a dedicated pin (FLTC) to program fault clear time. The EN/FLT needs to be outside 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.
