The LTC
廬
1693 family drives power 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. The
LTC1693-2 contains one noninverting and one inverting
driver. The LTC1693-1 and LTC1693-2 drivers are electri-
cally isolated and independent. The LTC1693-3 is a single
driver with an output polarity select pin.
The LTC1693 has V
CC
independent CMOS input thresh-
olds with 1.2V of typical hysteresis. The LTC1693 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. Both circuits 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.
