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 DS1640 requires a +3 Û +5 volt power supply input which is used to power internal logic and to operate a gate bias generator.
