Product Overview
The Microchip MIC2025-1YM TR is a single-channel high-side MOSFET power distribution switch optimized for USB power applications. Housed in an 8-pin SOIC package, it features 140mOhm maximum on-resistance, 500mA minimum continuous output current, and an operating voltage range of 2.7V to 5.5V. The device integrates short-circuit protection with thermal shutdown, a fault status flag with 3ms deglitch filter, undervoltage lockout, and soft-start circuitry for inrush current limiting during hot-plug events.
