MIC2033-08AYMT-T5

Overview

The MIC2033-08AYMT-T5 is a high-side, fixed current limit power switch from Microchip Technology. It provides 1:1 P-channel output with an 800mA maximum output current and a typical on-resistance of 75 milliohms. The device operates within a load voltage range of 2.5V to 5.5V and features a SOT-23-6 surface-mount package. It includes fault protection mechanisms such as fixed current limiting, thermal shutdown, and undervoltage lockout (UVLO). The component supports logic-controlled enable inputs and offers a status flag output.

Feature Summary

• Integrated fixed current limiting for precise overcurrent protection
• Controlled slew rate minimizes inrush current during startup
• Open-drain fault status flag indicates overcurrent or thermal events
• Thermal shutdown protects the device and system from overheating

Applications

• Power distribution systems requiring high-side switching
• Load protection in embedded electronic circuits
• Systems utilizing high capacitive loads with soft-start requirements

Procurement Notes

Verify the exact suffix against official Microchip documentation, as variations like -T5 or -TR indicate specific tape-and-reel packaging configurations. Confirm the part status, as certain MIC2033 variants have been marked obsolete. Ensure the selected version matches the required current limit and package type for your design.

Selection Notes

Select this component when a high-side switch with fixed 800mA current limiting is required. It is suitable for applications needing controlled turn-on times to manage inrush currents. Consider the SOT-23-6 package constraints and the 2.5V to 5.5V operating voltage range. Verify compatibility with active-high or active-low control logic if using standard MIC2033 variants.

Part Context

This part belongs to the MIC2033 family of high-accuracy power switches designed by Micrel, now Microchip Technology. The series is known for its ±5% current limit accuracy and pin compatibility with older MIC2005 devices. These switches are engineered to enhance system reliability through integrated fault protection and low quiescent current operation.
