TPS22968NDPUR TI Power Switch IC | 14-WSON (3x2) | 5.5V, 4A, Low Rds(on)

Product Overview

The TPS22968NDPUR from Texas Instruments is a high-performance load switch with controlled slew rate, designed for power management in space-constrained applications. Housed in a compact 14-WSON (3x2) package, it supports an input voltage range of 0.8V to 5.5V and can handle continuous currents up to 4A. The device features a low on-resistance (Rds(on)) of typically 14mΩ at 5V, minimizing power loss and heat dissipation. It includes an integrated quick output discharge (QOD) function to ensure fast discharge of output capacitance when the switch is turned off.
