Overview
- Dual MOSFET Drivers in SO-8 Package or Single MOSFET Driver in MSOP Package
- 1GΩ Electrical Isolation Between the Dual Drivers Permits High/Low Side Gate Drive
- 1.5A Peak Output Current
- 16ns Rise/Fall Times at VCC = 12V, CL = 1nF
- Wide VCC Range: 4.5V to 13.2V
- CMOS Compatible Inputs with Hysteresis, Input Thresholds are Independent of VCC
- Driver Input Can Be Driven Above VCC
- Undervoltage Lockout
- Thermal Shutdown
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.
