TPS2046BD TI Power Distribution Switch | 8-SOIC | 0.5A, 2.7-5.5V

Product Overview

The TPS2046BD from Texas Instruments is a single-channel, current-limited power-distribution switch designed for applications requiring precision current limiting and thermal protection. Housed in an 8-pin SOIC package, this device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. It features a typical current limit of 0.5A (adjustable via external resistor) and an enable input for ON/OFF control. The TPS2046BD integrates a 70mΩ N-channel MOSFET, ensuring low voltage drop and efficient power delivery. With built-in overcurrent, overtemperature, and reverse-current protection, it provides robust fault handling for USB ports, peripheral power, and hot-swap applications.
