TPS2555DRCT TI Power Switch | 10-VSON (3x3) | 1.5A, Adjustable Current Limit

Product Overview

The TPS2555DRCT from Texas Instruments is a precision adjustable current-limited power-distribution switch optimized for applications requiring high accuracy and robust protection. Housed in a compact 10-pin VSON (3x3 mm) package, it provides a 1.5A continuous current capability with an adjustable current-limit threshold via an external resistor. The device integrates N-channel MOSFET with low on-resistance (typical 70 mΩ) to minimize power loss and voltage drop. It features overcurrent, overtemperature, and reverse-current protection, making it ideal for USB ports, hot-swap, and general-purpose power management.
