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
µs
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 FETs designed as switches to conserve power in
personal computer systems. When connected to power management control units, power consuming
devices like disk drives or display panel backlights can be routinely shut down to conserve battery or
main power supply energy. The P channel power MOS FETs 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 Û +5 volt power supply input which is used to power internal logic and to operate a gate
bias generator.
