LTC4440AHMS8E-5#PBF

LTC4440A-5 is a high frequency high side N-channel MOSFET gate driver. It can also withstand and continue to function during 100V VIN transients. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitances. It features supply independent TTL/CMOS compatible input thresholds with 350mV of hysteresis. The input logic signal is internally level-shifted to the bootstrapped supply, which may function at upto 95V above ground. It is optimized for driving (5V) logic level FETs and contains an undervoltage lockout circuit that disables the external MOSFET when activated. It is used in application like automotive power systems, telecommunications power systems, distributed power architectures, server power supplies, high density power modules, general purpose low or high side driver.
