description  
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 mΩ) and one p-channel (1.3 Ω) 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  
0.75 µA 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.
