MIC2033-10BYMT-TR

Overview

The MIC2033-10BYMT-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 fixed current limit of 1A with ±5% accuracy. The device utilizes a SOT-23-6 package and includes thermal shutdown protection. It offers logic-controlled enable inputs, an open-drain fault status output with a 32ms delay, and soft-start capability via an external capacitor. The typical on-resistance is 75mΩ at 5V, with a quiescent current of 100µA when active.

Feature Summary

• High-accuracy current limiting with ±5% tolerance for reliable system protection
• Integrated thermal shutdown and undervoltage lockout mechanisms
• Configurable soft-start circuitry to minimize inrush currents
• Fault status flagging with built-in delay for stable operation

Applications

• Power distribution in embedded systems requiring high-side switching
• Protection circuits for loads with high capacitive requirements
• Portable electronic devices operating within low voltage ranges

Procurement Notes

Verify the specific suffix 'BYMT' against official Microchip documentation to confirm pinout and enable logic configuration. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the datasheet revision date to validate parameter consistency before integration into final designs.

Selection Notes

Select this component for applications requiring precise current limiting and compact packaging. The SOT-23-6 form factor suits space-constrained designs. Consider the 1A limit and 5.5V maximum rating against load requirements. Evaluate the need for soft-start functionality to manage startup transients effectively.

Part Context

This part belongs to the MIC2033 family of high-side power switches. It shares architectural similarities with other members like the MIC2005 but offers improved current accuracy. The series is designed for general-purpose power distribution where reliability and compact size are prioritized over high-current capabilities.

Replacement Considerations

The MIC2033 is pin-compatible with the MIC2005 series. Verify that substitute parts match the specific current limit and enable logic polarity required by the design.
