LM3526M-H/NOPB TI USB Power Switch | 8-SOIC | 2-Ch, 500mA, Current Limiting

Product Overview

The LM3526M-H/NOPB is a dual-channel USB power switch from Texas Instruments, designed for applications requiring current-limited power distribution. It integrates two independent 500mA switches with over-current and thermal protection, making it ideal for USB ports and other hot-swap applications. The device operates from a 2.7V to 5.5V input voltage range and features a low quiescent current of 1µA in shutdown mode. Housed in an 8-pin SOIC package, it provides a compact solution for power management in space-constrained designs.
