STMPS2141STR ST Power Distribution Switch | SOT-23-5 | 0.5A, Current Limiting

Product Overview

The STMPS2141STR is a single-channel, current-limited power distribution switch from STMicroelectronics, designed for applications requiring up to 0.5A of continuous current. Housed in a compact SOT-23-5 package, it integrates a 70mΩ N-channel MOSFET with over-current, thermal, and reverse-current protection. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for 3.3V and 5V power rails. Its enable pin is active-high, and the fault flag output indicates over-current or thermal shutdown conditions.
