1N5833

Overview

The MIC2033-55AYM6-TR is a high-side power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 2.5 V to 5.5 V and provides a fixed current limit of 550 mA with ±5% accuracy. The device features a maximum on-resistance of 177 mΩ, typical quiescent current of 100 µA, and thermal shutdown protection. It includes undervoltage lockout, soft-start control via an external capacitor, and an open-drain fault status output flag. The component is housed in a SOT-23-6 package and supports operation from -40°C to +125°C.

Feature Summary

• High-side MOSFET power distribution switch with 5% current limit accuracy
• Integrated thermal shutdown and undervoltage lockout for system protection
• Open-drain fault status output flag with built-in delay
• Capacitor-adjustable soft-start circuit to minimize inrush current

Applications

• Power distribution in systems with high capacitive loads
• Protection circuits requiring precise current limiting
• Embedded systems utilizing logic-controlled enable inputs

Procurement Notes

Verify the specific suffix 'AYM6' against official Microchip documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the operating environment stays within the specified temperature range of -40°C to +125°C. Confirm that the 550 mA current limit aligns with your load specifications to prevent unnecessary tripping or insufficient protection.

Selection Notes

Select this component when a high-side switch with fixed current limiting and fault reporting is required. It is suitable for applications needing low quiescent current and fast response to short circuits. Consider the SOT-23-6 package size for space-constrained designs. Verify compatibility with your system's logic levels for the active-high or active-low enable input.

Part Context

The MIC2033 series consists of high-accuracy, high-side power switches designed to enhance system reliability. Available in multiple current limit options (0.5A, 0.8A, 1A, 1.2A), it offers flexibility for various load requirements. The series is pin-compatible with the MIC2005, facilitating easier upgrades or replacements in existing designs while providing improved accuracy and integrated protection features.

Replacement Considerations

The MIC2033 is pin-compatible with the MIC2005. Verify that the substitute part matches the required current limit and package type. Consult official datasheets to ensure all electrical parameters, including voltage ranges and thermal characteristics, meet your application needs before replacing.
