描述
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.
The LTC4440-5 is available in the low profile (1mm) SOT-23 or a thermally enhanced 8-lead MSOP package.
