transients. The powerful driver capability reduces switch-  
ing 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.

TTL/CMOS Compatible Inputs with Hysteresis  
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.
