LTC1693 - High Speed Single/Dual MOSFET Driver
describe
The LTC®1693 series drives high power MOSFET speeds. The 1.5A peak output current reduces switching losses with high gate capacitance MOSFETs. The LTC1693-1 contains two non-inverting drivers. The LTC1693-2 contains a non-inverting and inverting one driver. The LTC1693-1 and LTC1693-2 drivers are galvanically isolated and independent. The LTC1693-3 is a single driver with an output polarity select pin. The LTC1693 has independent CMOS input thresholds for VCC with a typical hysteresis of 1.2V. The LTC1693 can level-shift the input logic signal up or down the rail torailVCC to drive an external MOSFET. The LTC1693 contains an undervoltage lockout circuit and thermal shutdown circuit. Both circuits are active when the external N-channel MOSFET gate driver is disabled. The LTC1693-1 and LTC1693-2 come in 8-lead SO packages. The LTC1693-3 comes in an 8-lead MSOP package.
