TPS2057D TI Power Distribution | 16-SOIC | 0.7A, 2.7-5.5V

Product Overview

The TPS2057D 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, it operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. Each channel can deliver up to 0.7A of continuous current, with an accurate current-limit threshold of 0.7A (typical). The device features a low on-resistance of 70mΩ per channel, minimizing power dissipation. It includes built-in thermal shutdown and reverse-current protection, ensuring robust operation in fault conditions. The TPS2057D is ideal for USB ports, peripheral power management, and hot-swap applications.
