Power-path mux for dual-rail portable designs
The Texas Instruments TPS2115ADRBTG4 is a 2:1 source selector switch that routes one of two input power rails to a single output, using an internal N-channel FET with a 2 A continuous output ceiling.
Switching delays and thermal footprint
Turn-on delay is 1 ms and turn-off delay is 5 ms, which sets the minimum hold-up time for the downstream regulator when switching between supplies.
