TYPICAL APPLICATIO

DESCRIPTIOU
The LTC
1693 family drives power N-channel MOSFETs
at high speed. The 1.5A peak output current reduces
switching losses in MOSFETs with high gate capacitance.
The LTC1693-1 contains two noninverting drivers while
the LTC1693-2 contains one noninverting and one invert-
ing driver. These dual drivers are electrically isolated and
independent. The LTC1693-3 is a single driver with an
output polarity select pin.
All MOSFET drivers offer V
CC
independent CMOS input
thresholds with 1.2V of typical hysteresis. They can level-
shift the input logic signal up or down to the rail-to-rail V
CC
drive for the external MOSFET.
The LTC1693 contains an undervoltage lockout circuit and
a thermal shutdown circuit that disable the external
N-channel MOSFET gate drive when activated.
The LTC1693-1 and LTC1693-2 come in an 8-lead SO pack-
age. The LTC1693-3 comes in an 8-lead MSOP package.
