General Description

The 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 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.
