DESCRIPTION
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
