Overview
The MIC2003-0.5YM5 is a single-channel, high-side power switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET architecture to manage load connections within electronic circuits. The device supports an input voltage range of 2.5V to 5.5V and delivers a continuous output current of 500mA. Key electrical characteristics include a typical on-resistance of 70 milliohms and non-inverted logic control. Integrated protection mechanisms provide fixed current limiting and thermal shutdown capabilities. The component operates reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.
Feature Summary
- High-side P-channel configuration for efficient load switching
- Integrated fixed current limiting and thermal shutdown protection
- Non-inverted logic interface for straightforward control
Applications
- Portable consumer electronics requiring overcurrent protection
- Peripheral device hot-swapping interfaces
- Battery-powered systems with load management needs
Procurement Notes
Verify the specific suffix YM5 against official Microchip documentation to confirm the exact package type and tape-and-reel specifications. Ensure the ordering part number matches the required lead time and manufacturing lot details. Cross-reference the datasheet revision history to validate compatibility with existing design constraints before finalizing procurement orders.
Selection Notes
Select this component when a single-channel high-side switch with integrated fault protection is required. The 500mA current rating suits low-power peripheral loads. Verify that the 2.5V minimum operating voltage aligns with the system supply rails. Consider the SOT-23-5 footprint for space-constrained PCB layouts requiring surface-mount assembly.
Part Context
This part belongs to the MIC2003 family of single-channel power switches. The series offers various current ratings and package options to accommodate different power distribution requirements. The MIC2003 variant specifically targets applications needing basic load switching with built-in safety features in a minimal footprint.
Replacement Considerations
Consult the official Microchip MIC20xx Family datasheet for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before substituting.
