TPS2556DRBR TI Power Switch | 8-SON(3x3) | 5.5V, 5A, Adjustable Current Limit

Product Overview

The TPS2556DRBR from Texas Instruments is a precision adjustable current-limited power-distribution switch designed for applications requiring up to 5A continuous current. Housed in a compact 8-SON (3x3 mm) package, it integrates a 70mΩ N-channel MOSFET with a programmable current-limit threshold via an external resistor. The device operates over a wide input voltage range of 2.5V to 5.5V, making it suitable for 3.3V and 5V power rails. It features fast overcurrent response (2µs typical) and thermal shutdown protection, ensuring robust operation in demanding environments.
