MIC2003-0.8YM5

Overview

The MIC2003-0.8YM5 is a single-channel, high-side power switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET architecture to manage load power distribution within electronic circuits. The device supports an input voltage range of 2.5V to 5.5V and delivers a continuous output current capability of 800mA. Key electrical characteristics include a typical on-resistance of 70 milliohms and non-inverting logic control. Integrated protection mechanisms provide fixed current limiting and thermal shutdown functionality to safeguard the load and the switch itself during fault conditions.

Feature Summary

• Integrates a high-side P-channel MOSFET for efficient power switching in low-voltage applications.
• Provides comprehensive fault protection through integrated fixed current limiting and thermal shutdown circuitry.
• Features a compact SOT-23-5 surface-mount package designed for space-constrained PCB layouts.

Applications

• Peripheral power management in portable consumer electronics
• Load switching in automotive infotainment systems
• Power distribution networks in industrial control modules

Procurement Notes

Verify that the specific suffix YM5 corresponds to the SOT-23-5 package configuration required for your design. Confirm that the 800mA current rating aligns with your maximum load requirements. Ensure compatibility with the 2.5V to 5.5V operating voltage range. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a single-channel high-side switch with moderate current capacity is needed. The 800mA rating suits applications requiring more power than standard 500mA switches but less than heavy-duty alternatives. Consider the 70mΩ on-resistance for efficiency calculations. The non-inverting interface simplifies control logic integration compared to active-low variants.

Part Context

This part belongs to the MIC2003 family of power switches from Microchip Technology. The family offers various current ratings and package options to suit different design constraints. The MIC2003 series is characterized by its robust protection features and low on-resistance, making it suitable for general-purpose power switching tasks in both commercial and industrial environments.
