ST890BDR ST Power Distribution Switch | 8-SOIC | 1.2A, 0.12Ω

Product Overview

The ST890BDR is a high-side power distribution switch from STMicroelectronics, designed for applications requiring robust current limiting and thermal protection. Housed in an 8-SOIC package, this device integrates a 0.12Ω N-channel MOSFET with a charge pump, providing up to 1.2A continuous current. It features active-high enable logic, undervoltage lockout (UVLO), and overcurrent protection with fault flag output. The ST890BDR is ideal for USB ports, hot-swap supplies, and general-purpose power management in industrial and consumer electronics.
