MIC2025-1YM

Overview

The MIC2025-1YM is a high-side power switch IC from Microchip Technology, designed for load distribution and protection. It features an N-channel MOSFET with a typical on-resistance of 90 milliohms and supports a maximum output current of 500mA. The device operates within a load voltage range of 2.7V to 5.5V and utilizes a non-inverting open/switch interface. Integrated fault protections include fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). Additional features comprise controlled slew rate and status flags for system monitoring.

Feature Summary

• Integrated high-side N-channel power switch with low on-resistance for efficient load driving
• Built-in fault protection mechanisms including fixed current limit, thermal shutdown, and under-voltage lockout
• Controlled slew rate functionality to minimize inrush currents and electromagnetic interference
• Status flag output providing real-time indication of switch state and fault conditions

Applications

• USB port power switching and protection
• Peripheral load distribution in embedded systems
• Hot-swap applications requiring controlled turn-on
• Battery-powered devices needing efficient power management

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint, as variations exist between SOIC and MSOP packages within the same base part number family. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component when a single-channel high-side switch with integrated protection is required for loads up to 500mA. It is suitable for 3.3V or 5V systems where controlled inrush current and fault monitoring are critical. Compare against other MIC2025 variants if multiple channels or different current ratings are needed. Ensure the operating temperature range meets your environmental constraints.

Part Context

This part belongs to the MIC2025 series of USB power switches manufactured by Microchip Technology. It is a single-channel device derived from Micrel's original design portfolio. The series is widely used in consumer electronics and industrial control for protecting downstream loads from overcurrent and short-circuit conditions while providing simple on/off control via a logic input.
