TPS2561DRCR TI Power Switch | 10-VSON (3x3) | Dual-Channel, 2.5A, Adjustable Current Limit

Product Overview

The TPS2561DRCR is a dual-channel, current-limited power-distribution switch from Texas Instruments, designed for applications requiring precision current limiting and robust protection. Housed in a compact 10-pin VSON (3x3 mm) package, it integrates two independent 70-mΩ N-channel MOSFETs with adjustable current-limit thresholds from 250 mA to 2.5 A per channel. The device operates over a wide input voltage range of 2.5 V to 6.5 V, making it suitable for 3.3-V and 5-V bus-powered systems. Key protection features include overcurrent, overtemperature, reverse-current blocking, and under-voltage lockout (UVLO). The TPS2561DRCR is ideal for USB ports, set-top boxes, and industrial automation where reliable power distribution is critical.
