2:1 power path mux for dual-rail handhelds
The TPS2113APWRG4 is a 2:1 source selector switch from Texas Instruments, designed to autonomously or manually select between two input power rails and deliver a single output up to 1.25 A. It integrates a pair of N-Channel MOSFETs in an 8-TSSOP package, making it a compact solution for dual-input battery or USB power management in handheld and mobile devices.
Switching delays and quiescent draw
The part features a 1 ms turn-on delay and a 5 ms turn-off delay, which sets the timing budget for glitch-free rail transitions. Its 55 µA supply current keeps the overhead low for battery-operated designs where every microamp matters.
