FEATURES  
DESCRIPTION  
The LTC®4440 is a high frequency high side N-channel  
MOSFET gate driver that is designed to operate in applica-  
tions with VIN voltages up to 80V. The LTC4440 can also  
withstand and continue to function during 100V VIN tran-  
sients. The powerful driver capability reduces switching  
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.  
■
Wide Operating VIN Range: Up to 80V  
■
Rugged Architecture Tolerant of 100V VIN  
Transients  
Powerful 1.5Ω Driver Pull-Down  
■
■
Powerful 2.4A Peak Current Driver Pull-Up  
■
7ns Fall Time Driving 1000pF Load  
■
10ns Rise Time Driving 1000pF Load  
■
Drives Standard Threshold MOSFETs  
■
TTL/CMOS Compatible Inputs with Hysteresis  
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.  
■
Input Thresholds are Independent of Supply  
■
Undervoltage Lockout  
Low Profile (1mm) SOT-23 (ThinSOT)TM or Thermally  
■
Enhanced 8-Pin MSOP Packages  
U
The LTC4440 contains both high side and low side under-  
voltage lockout circuits that disable the external MOSFET  
when activated.  
APPLICATIO S  
■
Telecommunications Power Systems  
■
Distributed Power Architectures  
The LTC4440 is available in the low profile (1mm) SOT-23  
or a thermally enhanced 8-lead MSOP package.
