LTC1693 pdf,LTC1693 datasheet

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 inverting
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 VCC independent CMOS input
thresholds with 1.2V of typical hysteresis. They can levelshift
the input logic signal up or down to the rail-to-rail VCC
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 package.
The LTC1693-3 comes in an 8-lead MSOP package.
