产品描述

The TPS2100 and TPS2101 are dual-input, single-output power switches designed to provide uninterrupted output voltage when transitioning between two independent power supplies. Both devices combine one n-channel (250 m) MOSFET with a single output. The p-channel MOSFET (IN2) is used with auxiliary power supplies that deliver lower current for standby modes. The n-channel MOSFET (IN1) is used with a main power supply that delivers higher current required for normal operation. Low on-resistance makes the n-channel the ideal path for higher main supply current when power-supply regulation and system voltage drops are critical. When using the p-channel MOSFET, quiescent current is reduced to 0.75uA to decrease the demand on the standby power supply. The MOSFETs in the TPS2100 and TPS2101 do not have the parasitic diodes, found in discrete MOSFETs, which allow the devices to prevent back-flow current when the switch is off.
