FEATURES
DESCRIPTIO
N
U
The LTC
4440 is a high frequency high side N-channel
MOSFET gate driver that is designed to operate in applica-
tions with V
IN
voltages up to 80V. The LTC4440 can also
withstand and continue to function during 100V V
IN
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 1.5
.
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.
The LTC4440 contains both high side and low side under-
voltage lockout circuits that disable the external MOSFET
when activated.
The LTC4440 is available in the low profile (1mm) SOT-23
or a thermally enhanced 8-lead MSOP package.
