MIC2033-10AYM6-TR

Overview

The MIC2033-10AYM6-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 provides a fixed current limit of 1A. The device features a typical on-resistance (RDS(ON)) of 75mΩ at 5V and includes thermal shutdown and undervoltage lockout (UVLO) protections. It utilizes a 6-pin SOT-23 package and offers logic-controlled enable inputs with an open-drain fault status flag.

Feature Summary

• High-accuracy ±5% fixed current limit 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 with built-in delay assertion

Applications

• Power distribution in portable electronic devices
• Load switching for high-capacitive loads requiring controlled inrush
• System reliability enhancement in industrial control circuits
• Protection of peripheral interfaces in embedded systems

Procurement Notes

Verify the specific suffix 'BYM6' against official Microchip documentation to confirm pinout and package dimensions, as variations exist within the MIC2033 family. Ensure the ordering part number matches the required current limit option (1A) and enable logic polarity. Cross-reference the datasheet revision history for any manufacturing changes or component updates that may affect compatibility.

Selection Notes

Select this component when a precise 1A current limit is required for high-side load management. The MIC2033-10 series is suitable for applications needing fast short-circuit response and adjustable soft-start capabilities. Consider the SOT-23-6 package constraints for PCB layout and ensure the operating temperature range meets the -40°C to +125°C junction requirement.

Part Context

The MIC2033 series comprises high-side MOSFET power switches designed to improve system reliability through accurate current limiting. This specific model belongs to the fixed current limit variant, distinct from the adjustable MIC2039 series. The device integrates protection features typically found in discrete solutions, offering a compact alternative for power distribution networks in low-voltage applications.

Replacement Considerations

MIC2033-08AYM6-TR: Offers 0.8A current limit; verify if lower capacity suffices. MIC2033-12AYM6-TR: Provides 1.2A limit; check if higher capacity is needed. MIC2033-05AYM6-TR: Supplies 0.5A limit; ensure adequate margin for load requirements.
