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.<\/p>\n

It is internally current limited and features thermal shutdown that protects the device and load. When a thermal shutdown fault occurs, the output is latched off until the faulty load is removed. Removing the load or toggling the enable input resets the device output. The device employs soft-start circuitry that minimizes inrush current in applications where highly capacitive loads are employed, making it ideal for USB power distribution and hot-plug applications.","working_principle":"The MIC2025-1YM TR operates as a high-side power switch between the input supply and the load. 1) Power Switch Subsystem: An internal N-Channel MOSFET with charge pump provides the low-resistance path from VIN to VOUT, with 140mOhm maximum on-resistance. 2) Current Limit Subsystem: A sense circuit monitors output current, limiting it to a safe preset level during overcurrent or short-circuit conditions. 3) Thermal Protection Subsystem: An on-die temperature sensor triggers shutdown when junction temperature exceeds the threshold, latching the output off until the fault is cleared. 4) Fault Flag Subsystem: An open-drain FLG output is asserted after a 3ms deglitch delay during overcurrent or thermal events, filtering out transient false triggers during hot-plug inrush.","pin_description":"
