Product Overview

The LTC4440AIMS8E-5#PBF is a high speed 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's 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.
  • Rugged architecture tolerant of 100V VIN transients
  • Powerful 1.85R driver pull-down (with 6V supply)
  • Powerful 1.1A peak current driver pull-up (with 6V supply)
  • 7ns Fall time driving 1000pF load
  • 10ns rise time driving 1000pF load
  • Drives standard threshold MOSFETs
  • TTL/CMOS compatible inputs with hysteresis
  • Input thresholds are independent of supply
  • Under-voltage lockout
