Overview
The TPS22992RXPR, produced by Texas Instruments, is a single-channel load switch integrated circuit (IC) designed to maximize power density in various applications. This device is part of the TPS22992x product family, which includes the TPS22992 and TPS22992S models. The TPS22992RXPR features an 8.7-mΩ power MOSFET, enabling it to handle up to 5.5 V and 6 A of continuous current. It is particularly useful for power sequencing and minimizing inrush current in high capacitance loads. The device is controlled via an enable pin that can interface directly with low voltage GPIO signals and includes an optional quick output discharge (QOD) pin for adjustable fall times.
