Description
The LTC®1693-5 drives power P-channel MOSFETs at high speed. The 1.5A peak output current reduces switching losses in MOSFETs with high gate capacitance.The LTC1693-5 is a single driver with an output polarity select pin. The MOSFET driver offers VCC independent CMOS input thresholds with 1.2V of typical hysteresis. It can level-shift the input logic signal up or down to the rail-to-rail VCC drive for the external MOSFET.
The LTC1693-5 contains an undervoltage lockout circuit and a thermal shutdown circuit that disables the external P-channel MOSFET gate drive if activated.
The LTC1693-5 comes in an 8-lead MSOP package.
