TPS2053BD TI Power Distribution | 16-SOIC | 0.7A, 2.7-5.5V

Product Overview

The TPS2053BD 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 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 accuracy of ±10% over temperature. The TPS2053BD integrates under-voltage lockout (UVLO), over-current protection, and thermal shutdown to ensure robust system reliability. Its low quiescent current (typically 50µA) and fast response time (2µs typical) make it ideal for hot-swap and USB applications.
