descriptionThe TPS2102 and TPS2103 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 mW ) and one p-channel (1.3 W ) 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
0.75m A to decrease the demand on the standby power supply. The MOSFETs in the TPS2102 and TPS2103
do not have the parasitic diodes, typically found in discrete MOSFETs, thereby preventing back-flow current
when the switch is off.
