MIC2033-05AYM6-T5

Overview

The MIC2033-05AYM6-T5 is a high-side, fixed current limit power switch designed for power distribution applications. It features an operating input voltage range from 2.5V to 5.5V and provides a typical on-resistance of 75mΩ at 5V. The device incorporates a 0.5A current limit with ±5% accuracy, ensuring precise load protection. It includes undervoltage lockout (UVLO), thermal shutdown, and a fault status output flag with a built-in 32ms delay. The component utilizes a 6-pin SOT-23 package and supports soft-start control via an external capacitor.

Feature Summary

• High-accuracy current limiting with ±5% tolerance for reliable load protection
• Integrated fault management including thermal shutdown and undervoltage lockout
• Open-drain fault status output flag with configurable delay assertion
• Capacitor-adjustable soft-start circuit to minimize inrush current

Applications

• Power distribution switches in embedded systems
• Load protection for high-capacitive loads requiring controlled inrush
• Overcurrent protection circuits for low-voltage digital logic
• Thermal management in portable electronic devices

Procurement Notes

Verify the specific suffix 'T5' against official Microchip documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the active-high enable logic matches system requirements, as variants exist with different control polarities. Cross-reference the exact part number with the latest datasheet revision to confirm pinout compatibility and package dimensions before finalizing procurement orders.

Selection Notes

Select this component when precise current limiting is required for loads up to 0.5A within a 2.5V to 5.5V supply range. Choose the SOT-23-6 package for space-constrained designs requiring surface-mount installation. Consider the external soft-start capability if the application involves significant capacitive loading that necessitates controlled turn-on times to prevent voltage droop.

Part Context

The MIC2033 series belongs to Microchip's family of high-side power distribution switches, offering enhanced system reliability through accurate current limiting. This specific model represents the 0.5A variant within the lineup, which also includes 0.8A, 1A, and 1.2A options. The series is designed to replace discrete MOSFET solutions by integrating protection features directly into a compact package.

Replacement Considerations

The MIC2005 is noted as pin-compatible with the MIC2033 series; however, verify functional differences in current limit accuracy and enable logic polarity before substitution. No other direct substitute part numbers are confirmed in the provided documentation.
