MIC2033-10AYMT-TR

Overview

The MIC2033-10AYMT-TR is a high-side power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 2.5V to 5.5V and features a typical on-resistance of 75mΩ at 5V. The device provides a fixed current limit of 1A with ±5% accuracy. It includes thermal shutdown protection, undervoltage lockout, and a fault status output flag with a 32ms delay. The component is housed in a 6-pin SOT-23 package and supports operation from -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
• Capacitor-adjustable soft-start circuit to minimize inrush current
• Open-drain fault status output flag indicating over-current or thermal events

Applications

• Power distribution in embedded systems requiring high-side switching
• Protection circuits for loads with high capacitive requirements
• System reliability enhancement in industrial control environments

Procurement Notes

Verify the specific suffix 'YMT' against official Microchip documentation to confirm package type and enable logic configuration. Ensure compatibility with existing PCB footprints for the 6-pin SOT-23 form factor. Confirm that the 1A current limit rating aligns with the target load specifications before integration.

Selection Notes

Select this component when precise current limiting accuracy is required for high-side applications. The 1A limit suits moderate load protection needs. Consider the external capacitor requirement for soft-start timing if inrush current management is critical. Verify that the 2.5V to 5.5V supply range matches the system's available voltage rails.

Part Context

This part belongs to the MIC2033 family of high-side power switches designed for robust power distribution. It shares pin compatibility with the MIC2005 series, facilitating design upgrades. The device integrates MOSFET technology to provide low on-resistance and efficient power handling within a compact surface-mount package.

Replacement Considerations

The MIC2033 is pin-compatible with the MIC2005 series. Verify functional equivalence regarding current limit values and enable logic polarity when substituting.
