LTC1693-5
High Speed Single
P-Channel MOSFET Driver
DESCRIPTIO
The LTC^®1693-5 drives power P-channel MOSFETs at
high speed. The 1.5A peak output current reduces switch-
ing losses in MOSFETs with high gate capacitance.
The LTC1693-5 is a single driver with an output polarity
select pin. The MOSFET driver offers V_CC independent
CMOS input thresholds with 1.2V of typical hysteresis. It
can level-shift the input logic signal up or down to the rail-
to-rail V_CC drive for the external MOSFET.
The LTC1693-5 contains an undervoltage lockout circuit
and a thermal shutdown circuit that disables the external
P-channel MOSFET gate drive if activated.
The LTC1693-5 comes in an 8-lead MSOP package.
