General Description

VCC GND IN1-IN4 OUT1-OUT4 GATE1-GATE4 NC LATCH - +3 to +5 Volt Input - Ground - FET Sources - FET Drains - FET Control Gates - No Connection - Gate Inputs Latch Control DESCRIPTION The DS1640 contains four P channel power MOS FETs designed as switches to conserve power in personal puter 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.

Key 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 Design.
