Power of Multiplexers The TPS211xA series enables two power supplies, such as a battery and a wall adapter, each operating at 2.8-5.5 V and providing up to one answer The TPS211xA series includes a wide range of protection circuitry, including user-programmable current limiting for seamless transitions, overheat protection, inrush current control, providing seamless transitions, cross-conduction blocking, and reverse conduction blocking. These features greatly simplify the design of power multiplexing applications.
