Product Introduction

Overview

The TPS2044BDR is a quad power-distribution switch from Texas Instruments, designed for applications where heavy capacitive loads and short circuits are likely to be encountered. This device incorporates four 70mΩ N-channel MOSFET high-side power switches in a single 16-pin SOIC (D) package. Each switch is controlled by a logic enable input and features an internal charge pump that minimizes current surges during switching. The TPS2044BDR operates over a voltage range of 2.7V to 5.5V and is suitable for power-distribution systems requiring multiple power switches in a compact package.
