MIC2004-1.2YM5

Overview

The MIC2004-1.2YM5 is a single-channel high-side power distribution switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET to manage load connections in systems operating between 2.5V and 5.5V. The device provides a maximum output current of 1.2A with a typical on-state resistance of 125 milliohms. It integrates fixed current limiting and thermal shutdown protection to safeguard connected loads. Designed for surface-mount assembly, it is housed in a compact SOT-23-5 package suitable for space-constrained applications.

Feature Summary

• Integrates fixed current limiting and thermal shutdown for robust fault protection
• Utilizes a low-resistance P-channel MOSFET for efficient high-side switching
• Features non-inverted logic control interface for straightforward system integration

Applications

• Portable consumer electronics requiring overcurrent protection
• Peripheral power management in embedded computing systems
• Battery-powered devices needing efficient load switching

Procurement Notes

Verify the specific suffix 'YM5' confirms the SOT-23-5 package variant. Ensure the '1.2' designation matches the required 1.2A current limit for your design. Confirm RoHS compliance status if environmental regulations apply. Check datasheet revisions for any pinout or electrical parameter updates before finalizing procurement.

Selection Notes

Select this component when a single-channel high-side switch with fixed current limiting is required. It is appropriate for loads drawing up to 1.2A within a 2.5V to 5.5V supply range. Consider the SOT-23-5 footprint constraints and thermal performance under continuous load conditions relative to your PCB layout capabilities.

Part Context

This part belongs to the MIC2004 family of power distribution switches from Microchip Technology, formerly Micrel. These devices are designed for general-purpose load switching applications where compact size and integrated protection features are prioritized. The family offers various current ratings and package options to suit different power and space requirements.

Replacement Considerations

Direct substitutes include other MIC2004 variants with compatible current limits and packages. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
