MIC2033-08AYM6-TR

Overview

The MIC2033-08AYM6-TR is a high-side power distribution switch from Microchip Technology, designed for system reliability. It features an operating input voltage range of 2.5V to 5.5V and provides a fixed current limit of 0.8A with ±5% accuracy. The device utilizes a P-channel MOSFET architecture housed in a SOT-23-6 package. Key electrical parameters include a typical on-resistance (RDS(ON)) of 75mΩ at 5V and a typical quiescent current of 100µA when enabled. It incorporates thermal shutdown and undervoltage lockout (UVLO) protections.

Feature Summary

• High-accuracy fixed current limiting capability
• Integrated thermal shutdown protection
• Capacitor-adjustable soft-start circuitry
• Open-drain fault status output flag

Applications

• Power distribution systems requiring load protection
• Applications with high capacitive loads necessitating inrush current control
• Embedded systems utilizing logic-level enable controls

Procurement Notes

Verify the specific suffix 'YM6' confirms the SOT-23-6 surface-mount package configuration. Confirm the '-TR' designation indicates tape-and-reel packaging suitable for automated assembly processes. Ensure compatibility with the required 0.8A current limit specification for the target load. Validate that the active-high or active-low logic level requirements match the system design constraints.

Selection Notes

Select this component when a high-side switch with precise current limiting is required. The 0.8A rating suits moderate load applications within the 2.5V to 5.5V supply range. Consider the soft-start feature if driving large capacitive loads to prevent voltage sag. The SOT-23-6 package offers a compact footprint for space-constrained designs compared to larger packages.

Part Context

This part belongs to the MIC2033 family of high-side power switches. The family includes variants with different current limits such as 0.5A, 1A, and 1.2A. The MIC2033 series is pin-compatible with the MIC2005 family, facilitating potential design upgrades or replacements where higher accuracy or specific protection features are needed.

Replacement Considerations

MIC2033-08AYM6-T5 is a pin-compatible variant within the same family offering identical electrical characteristics but differing in reel quantity specifications.
