TPS2043DR TI Power Distribution | 16-SOIC | 0.5A, 2.7-5.5V

Product Overview

The TPS2043DR from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for applications requiring precision current limiting and thermal protection. Housed in a 16-pin SOIC package, this device provides independent enable control for each channel, making it ideal for USB ports, peripheral power management, and other hot-swap applications. With a continuous output current of 0.5A per channel and an operating voltage range of 2.7V to 5.5V, it offers robust protection against overcurrent, overtemperature, and reverse current.

Detailed Technical Specifications

Key Features

• Dual-channel independent power distribution with enable control
