TPS2057DR TI Power Distribution | 16-SOIC | 0.7A, 2.7-5.5V

Product Overview

The TPS2057DR 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 compact 16-SOIC package, this device provides two independent 0.7A (minimum) current-limited outputs, operating from a supply voltage range of 2.7V to 5.5V. It features an enable input for each channel, fault reporting via open-drain outputs, and built-in thermal shutdown to protect against overcurrent and overtemperature conditions. The TPS2057DR is ideal for USB ports, peripheral power management, and other hot-swap applications where robust protection and small footprint are critical.
