Introduction

The TPS22949ADRGR, developed by Texas Instruments, is a sophisticated power distribution switch designed for efficient power management and load driving in electronic devices.

Product Features and Performance

Designed for Power Management (PMIC) in Power Distribution Switches, and Load Drivers categories.

Features two output channels, supporting a 1:1 input-to-output ratio.

High Side output configuration with P-Channel output type.

Operates with load voltages ranging from 1.62V to 4.5V.

Automatically restarts under fault conditions and includes load discharge capabilities.

Incorporates fixed current limiting and over-temperature fault protection for enhanced safety.

Compatible with non-inverting input signals.

Operates effectively within a -40°C to 105°C temperature range.

Available in an 8-SON (3x3) package for surface mount applications.
