TPS2048D TI Power Distribution Switch | 16-SOIC | 2.7-5.5V, 0.5A, Dual USB

Product Overview

The TPS2048D from Texas Instruments is a dual-channel power distribution switch designed for applications requiring precise current limiting and overcurrent protection. Housed in a 16-pin SOIC package, this device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for USB and general-purpose power management. Each channel can deliver up to 500mA of continuous current, with an integrated current-limiting circuit that protects the host device and downstream components from fault conditions. The TPS2048D features a low on-resistance of typically 70mΩ, minimizing power dissipation and voltage drop. It also includes thermal shutdown protection to prevent damage under extreme conditions. The device is fully specified over the industrial temperature range of -40°C to +85°C.
