MIC2033-08AYMT-TR

Overview

The MIC2033-08AYMT-TR is a high-side power distribution switch from the MIC2033 family, manufactured by Microchip Technology. It integrates a P-channel MOSFET with fixed current limiting and thermal protection for system reliability. The device operates within an input voltage range of 2.5V to 5.5V and features a typical on-resistance of 75mΩ at 5V. It includes an open-drain fault status flag with a 32ms delay, undervoltage lockout (UVLO), and soft-start control via an external capacitor. The component is housed in a 6-pin SOT-23 package.

Feature Summary

• High-accuracy ±5% fixed current limit for precise load protection
• Integrated thermal shutdown and undervoltage lockout (UVLO)
• Open-drain fault status output with built-in delay
• Capacitor-adjustable soft-start to minimize inrush current

Applications

• Power distribution in embedded systems
• Load switching for high-capacitive loads
• Protection circuits for peripheral devices

Procurement Notes

Verify the specific suffix 'T' against official Microchip documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the active state matches project requirements, noting that related variants may have different obsolescence statuses.

Selection Notes

Select this component when a high-side switch with accurate current limiting is required for 2.5V to 5.5V systems. The 0.8A current limit option suits moderate load applications. Consider the SOT-23-6 package for space-constrained designs. Verify logic level compatibility for the enable pin and ensure adequate thermal management for the operating junction temperature range.

Part Context

The MIC2033 series provides high-side switching solutions with enhanced reliability through precise current limiting. This model belongs to the broader MIC2033 family, which offers various current limit options including 0.5A, 1A, and 1.2A. The series is designed for applications requiring robust protection against overcurrent and thermal events in low-voltage environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the MIC2033 family, such as MIC2033-05 or MIC2033-10 variants, depending on current requirements. Verify if older Micrel-branded equivalents are available if sourcing from legacy channels.
