1 / 4 page 1 of 4 111999 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 PIN ASSIGNMENT PIN DESCRIPTION VCC - +3 to +5 Volt Input GND - Ground IN1-IN4 - FET Sources OUT1-OUT4 - FET Drains GATE1-GATE4 - FET Control Gates NC - No Connection LATCH - Gate Inputs Latch Control 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.
