DS1640/DS1640C
Personal Computer Power FET
DS1640/DS1640C
022698 1/4
FEATURES
Contains four P channel power FET switches that can
each supply over 300 mA @ 0.2 volts drop
Controlled directly from CMOS or TTL level signals
Fast switching time of less than 10
μ
s at rated supply
current
16-pin DIP or 16-pin SOIC surface mount package
Positive logic signal turns each FET on and ground or
low level signal turns each FET off
Off condition allows less than 50 nA of current flow
Low control gate capacitance of less than 5 pF
FET gates can either follow inputs or be latched
Designed for use with power supplies ranging from +3
to +5 volts

DESCRIPTION
The DS1640 contains four P channel power MOS FET’s
designed as switches to conserve power in personal
computer systems. When connected to power man-
agement control units, power consuming devices like
disk drives or display panel backlights can be routinely
shut down to conserve battery or main power supply en-
ergy. The P channel power MOS FET’s are individually
controlled and are capable of handling 300 mA each
continuously with less than 0.2 volts drop from input to
output. The device requires a +3
+5 volt power supply
input which is used to power internal logic and to oper-
ate a gate bias generator.
