TPS2048AD TI Power Distribution | 16-SOIC | 4-Ch, 0.5A, 2.7-5.5V

Product Overview

The TPS2048AD from Texas Instruments is a quad-channel power-distribution switch designed for applications requiring multiple independent power rails. Each channel provides up to 0.5A continuous current with a typical on-resistance of 70mΩ. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. Built-in overcurrent, thermal, and reverse-current protection ensure robust operation in demanding environments. The 16-SOIC package offers a compact footprint for space-constrained designs.

Detailed Technical Specifications
