Linear Technology LTC4440ES6-5#TRMPBF

Description
The LTC4440-5 is a high-speed, high-voltage, high-side gate driver designed for applications with VIN voltages up to 60V. It can withstand and continue to function during 80V VIN transients. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitances. The LTC4440-5's pull-up has a peak output current of 1.1A and its pull-down has an output impedance of 1.85Ω.
The LTC4440-5 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 LTC4440-5 is optimized for driving (5V) logic level FETs and contains an undervoltage lockout circuit that disables the external MOSFET when activated.
