LTC1693

High Speed Single/Dual

N-Channel MOSFET Drivers

FEATURES

DESCRIPTIO

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 V

= 12V, C

= 1nF

Wide V

Range: 4.5V to 13.2V

CMOS Compatible Inputs with Hysteresis,

Input Thresholds are Independent of V

Driver Input Can Be Driven Above V

Undervoltage Lockout

Thermal Shutdown

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 invert-

ing 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 V

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 V

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 pack-

age. The LTC1693-3 comes in an 8-lead MSOP package.
