TPS22902BYFPR TI Power Switch IC | 4-DSBGA | 5.5V, 2A, 60mΩ

Product Overview

The TPS22902BYFPR from Texas Instruments is a high-performance, single-channel load switch with controlled slew rate and low on-resistance. Housed in a compact 4-DSBGA package, it supports input voltages from 0.8V to 5.5V and continuous currents up to 2A. The device features an ultra-low on-resistance of 60mΩ (typical) to minimize power loss and voltage drop. It includes a quick output discharge (QOD) function to rapidly discharge the output capacitance when the switch is disabled, ensuring safe operation in power sequencing applications.
