Overview
The TPS2116DRLR, produced by Texas Instruments, is a low-IQ, priority power multiplexer designed for efficient power management in various applications. This device operates within a voltage range of 1.6 V to 5.5 V and can handle a maximum continuous current of 2.5 A. It utilizes N-channel MOSFETs to switch between two input supplies, providing a controlled output slew rate when voltage is first applied. The TPS2116DRLR is particularly suited for systems where battery life is a critical factor due to its ultra-low quiescent current of 1.32 µA (typical) and standby current of 50 nA (typical).
