LTC1693-5
High Speed Single
P-Channel MOSFET Driver
DESCRIPTIO
The LTC®1693-5 drives power P-channel MOSFETs at
high speed. The 1.5A peak output current reduces switch-
ing 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.

PIN FUNCTIONS
IN (Pin 1): Driver Input. The input has VCC independent
thresholds with hysteresis to improve noise immunity.
NC (Pins 2, 5, 6): No Connect.
PHASE (Pin 3): Output Polarity Select. Connect this pin to
VCC or leave it floating for noninverting operation. Ground
this pin for inverting operation. The typical PHASE pin
input current when pulled low is 20µA.
GND (Pin 4): Driver Ground. Connect to a low impedance
ground. The VCC bypass capacitor should connect directly
to this pin.
OUT (Pin 7): Driver Output.
VCC (Pin 8): Power Supply Input. The source of the exter-
nal P-MOSFET should also connect directly to this pin.
This minimizes the AC current path and improves signal
integrity.
