The is a high frequency high-side N-channel MOSFET Gate Driver designed to operate in applications with VIN voltages up to 80V. The LTC4440A-5 can also withstand and continue to function during 100V VIN transients. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitances. The LTC4440A-5 pull-up has a peak output current of 1.1A and its pull-down has an output impedance of 1.85R. The LTC4440A-5 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 up to 95V above ground. The LTC4440A-5 is optimized for driving 5V logic level FETs and contains an under-voltage lockout circuit that disables the external MOSFET when activated.
