MIC2033-05AYMT-TR

Overview

The MIC2033-05AYMT-TR is a high-side power distribution switch manufactured by Microchip Technology. It features an operating input voltage range of 2.5V to 5.5V and provides a fixed current limit of 0.5A with ±5% accuracy. The device includes thermal shutdown protection, undervoltage lockout (UVLO), and a fault status output flag with a 32ms delay. It utilizes a 6-pin SOT-23 package and operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• High-accuracy current limiting with ±5% tolerance for reliable system protection
• Integrated thermal shutdown and undervoltage lockout mechanisms
• Fault status output flag with built-in delay for overcurrent or thermal events
• Capacitor-adjustable soft-start circuit to minimize inrush current

Applications

• Power distribution in portable electronic devices
• Peripheral power switching in embedded systems
• Battery-powered equipment requiring high-side load control

Procurement Notes

Verify the specific suffix '05A' confirms the 0.5A current limit variant. Confirm the 'YMT' suffix corresponds to the 6-pin SOT-23 package type. Ensure the '-TR' suffix indicates tape-and-reel packaging if required for assembly. Cross-reference the manufacturer part number with official Microchip documentation to validate active status and revision history before procurement.

Selection Notes

Select this component when a high-side switch with precise 0.5A current limiting is required. It is suitable for applications needing thermal protection and fault signaling. Consider the 2.5V to 5.5V supply range compatibility. Evaluate the need for external soft-start capacitance based on load characteristics. Compare against other MIC2033 variants if different current limits or enable logic polarities are needed.

Part Context

The MIC2033 series comprises high-side MOSFET power switches designed for system reliability. This specific model belongs to the family offering fixed current limit options including 0.5A, 0.8A, 1A, and 1.2A. It shares pin compatibility with the MIC2005 series and is available in both SOT-23 and thin DFN packages. The series emphasizes low quiescent current and fast short-circuit response times.

Replacement Considerations

Direct substitutes include other MIC2033 variants with matching current limits and package types. Verify pin compatibility with MIC2005 series devices if migrating from older designs. Ensure replacement parts maintain the same voltage range and thermal specifications.
