transients. The powerful driver capability reduces switch-  
ing losses in MOSFETs with high gate capacitances. The  
LTC4440’s pull-up has a peak output current of 2.4A and  
its pull-down has an output impedance of 1.5Ω.

The LTC4440 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 115V  
above ground.  
Low Profile (1mm) SOT-23 (ThinSOT)™ and  
Thermally Enhanced 8-Pin MSOP Packages  
APPLICATIONS  
The LTC4440 contains both high side and low side under-  
voltage lockout circuits that disable the external MOSFET  
when activated.
