MIC2033-05BYMT-TR

Overview

The MIC2033-05BYMT-TR is a high-side power distribution switch from Microchip Technology, designed for system reliability. It features a fixed current limit of 500 mA with ±5% accuracy and an operating input voltage range of 2.5 V to 5.5 V. The device includes thermal shutdown protection and a fault status output flag with a 32 ms delay. It offers soft-start control via an external capacitor to minimize inrush current. The component operates within a junction temperature range of -40°C to +125°C and is available in a 6-pin SOT-23 package.

Feature Summary

• High-accuracy fixed current limit with ±5% tolerance
• Integrated thermal shutdown and undervoltage lockout (UVLO)
• Fault status output flag with built-in 32 ms delay
• Soft-start capability using an external capacitor

Applications

• Power distribution in portable electronic devices
• Load switching in industrial control systems
• Overcurrent protection for peripheral circuits
• Hot-plug applications requiring controlled inrush current

Procurement Notes

Verify the specific suffix 'BYMT' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the part number matches the exact current limit variant required for the design. Cross-reference the datasheet revision date to confirm compatibility with existing system requirements. Confirm RoHS compliance status through manufacturer declarations. Validate that the ordering information aligns with the intended application environment.

Selection Notes

Select this component when a high-side switch with precise current limiting is required. The fixed 500 mA limit suits loads needing consistent overcurrent protection without adjustable thresholds. Consider the 2.5 V to 5.5 V input range for low-voltage digital logic interfaces. The integrated fault flag simplifies monitoring compared to switches lacking status outputs. Evaluate the soft-start feature if driving capacitive loads to prevent voltage droop.

Part Context

The MIC2033 series comprises high-side power switches offering various fixed current limits including 0.5 A, 0.8 A, 1 A, and 1.2 A options. These devices share common features such as thermal shutdown, UVLO, and fault reporting. The series is pin-compatible with earlier models like the MIC2005, facilitating upgrades. Variants differ primarily in current rating and enable logic polarity, providing flexibility for diverse power management architectures.
