MIC2033-12BYM6-TR

Overview

The MIC2033-12BYM6-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 1.2A with ±5% accuracy. The device includes thermal shutdown protection, undervoltage lockout (UVLO), and a soft-start circuit controlled by an external capacitor. It provides a fault status output flag that asserts low during overcurrent or thermal events. The component is housed in a 6-pin SOT-23 package and supports operation across a junction temperature range of -40°C to +125°C.

Feature Summary

• High-accuracy current limiting with ±5% tolerance for reliable load protection
• Integrated thermal shutdown and undervoltage lockout for system safety
• Capacitor-adjustable soft-start capability to minimize inrush currents
• Open-drain fault status output flag with built-in delay for monitoring

Applications

• Power distribution in portable electronic devices
• Load switching in battery-powered systems
• Protection circuits for high-capacitive loads
• Embedded system power management modules

Procurement Notes

Verify the specific suffix BYM6 corresponds to the required current limit option and package variant. Confirm RoHS compliance status through official documentation. Ensure ordering quantities align with manufacturer reel specifications. Cross-reference the datasheet revision date to guarantee parameter accuracy for the production batch.

Selection Notes

Select this component when a high-side switch with precise current limiting is required. The 1.2A limit suits moderate load applications. Consider the soft-start feature if driving large capacitive loads. Verify logic level compatibility for the enable input. Ensure the operating voltage range matches the system supply rails.
