ST890CDR ST Power Distribution Switch | 8-SOIC | 0.5A, 2.7-5.5V

Product Overview

The ST890CDR is a high-side power distribution switch from STMicroelectronics, designed for applications requiring up to 0.5A continuous current. It integrates a 70mΩ N-channel MOSFET with thermal and short-circuit protection, making it ideal for USB and general-purpose power management. The device operates from 2.7V to 5.5V and features a logic-level enable input, fault flag output, and controlled slew rate to minimize inrush current.
