MIC2033-10BYM6-T5

Overview

The MIC2033-10BYM6-T5 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. The device utilizes a P-channel MOSFET architecture housed in a SOT-23-6 surface-mount package. Key electrical characteristics include a typical on-resistance of 75mΩ at 5V and a typical quiescent current of 100µA when enabled. The component supports an operating junction temperature range from -40°C to +125°C and includes undervoltage lockout protection.

Feature Summary

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

Applications

• Power distribution in portable consumer electronics
• Load switching in automotive infotainment systems
• Peripheral power management in industrial control units
• Battery-powered device load protection circuits

Procurement Notes

Verify the specific suffix 'T5' against official Microchip documentation to confirm reel quantity and tape specifications, as packaging details can vary. Ensure the sourcing channel provides valid RoHS compliance certificates consistent with Microchip's environmental declarations. Cross-reference the manufacturer part number with the latest datasheet revision to confirm active status and any potential manufacturing changes or obsolescence notices prior to procurement.

Selection Notes

Select this component when a precise 1A current limit is required for high-side switching applications. The fixed current limit offers higher accuracy compared to adjustable variants, simplifying design calculations. Consider the SOT-23-6 package for space-constrained layouts. Evaluate the need for the open-drain fault flag if system monitoring is necessary. Ensure the load capacitance requirements align with the external soft-start capacitor capabilities to manage turn-on transients effectively.

Part Context

This part belongs to the MIC2033 family of high-accuracy, high-side power switches. It shares pin compatibility with the MIC2005 series but offers improved current limit accuracy. The family provides multiple current options including 0.5A, 0.8A, 1A, and 1.2A variants. The MIC2033-10BYM6-T5 specifically denotes the 1A limit version in the SOT-23-6 package with T5 trailing edge tape and reel packaging.

Replacement Considerations

• MIC2033-08AYM6-T5 (0.8A variant, same package)
• MIC2033-12BYM6-T5 (1.2A variant, same package)

FAQ

How is the soft-start time determined?

The soft-start time is controlled by connecting an external capacitor to the SS/EN pin. The charging rate of this capacitor dictates the ramp-up time of the gate drive, thereby limiting inrush current.

What triggers the fault status output flag?

The open-drain fault flag asserts low during over-current conditions or thermal shutdown events. It includes a built-in delay to prevent false triggering from transient noise.
