The TPS211xA family includes extensive protection circuitry, including userprogrammable current limiting, thermal protection, inrush current control, seamless supply transition, cross-conduction blocking, and reverse-conduction blocking. These features greatly simplify designing power multiplexer applications. space IN1: 2.8 V to 5.5 V TYPICAL APPLICATION TPS2113A 1 STAT 2 EN 3 VSNS 4 ILIM 8 IN1 7 OUT 6 IN2 5 GND Switch Status 0.1 mF R1 CL RL RILIM IN.
