Product Details

The LTC1693 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 level-shift 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.
