MIC2033-05BYM6-T5

Overview

The MIC2033-05BYM6-T5 is a high-side power distribution switch from Microchip Technology, designed for reliable load protection in low-voltage systems. It features a fixed current limit of 500mA and an on-resistance maximum of 177 mΩ. The device operates within an input voltage range of 2.5V to 5.5V and supports junction temperatures from -40°C to +125°C. Key electrical parameters include a maximum turn-on time of 700µs and a maximum fault response time of 5µs. Packaged in SOT-23-6, it integrates thermal shutdown and undervoltage lockout for comprehensive circuit safeguarding.

Feature Summary

• High-accuracy fixed current limiting with ±5% tolerance for precise load protection
• Integrated open-drain fault status flag with built-in delay for system monitoring
• Capacitor-adjustable soft-start capability to minimize inrush currents during startup
• Robust protection mechanisms including thermal shutdown and undervoltage lockout

Applications

• Power distribution networks in embedded industrial control systems
• Load switching and protection for peripheral devices in consumer electronics
• Overcurrent protection circuits in automotive infotainment and body modules
• Voltage regulation stages requiring controlled ramp-up for capacitive loads

Procurement Notes

Verify the specific suffix 'T5' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the 'BYM6' designation aligns with the required SOT-23-6 package variant and temperature grade. Cross-reference the active status with official Microchip channels to avoid obsolete stock. Confirm RoHS compliance details match project requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-side switch with a strict 500mA current limit is required for 2.5V to 5.5V systems. It is suitable for applications needing fast short-circuit response and adjustable soft-start timing via external capacitance. Consider the 177mΩ maximum on-resistance for efficiency calculations. Choose this part over adjustable variants if fixed current protection simplifies the design and reduces component count.

Part Context

This device belongs to the MIC2033 family of high-side power switches, which are pin-compatible with earlier Micrel products like the MIC2005. The family offers various current limit options ranging from 0.5A to 1.2A. The MIC2033-05BYM6-T5 specifically utilizes the 0.5A limit option. It shares common features such as logic-controlled enable inputs and fault flags across the series, ensuring design consistency within Microchip's power distribution portfolio.

Replacement Considerations

Publicly confirmed substitutes include other MIC2033 variants with different current limits (e.g., MIC2033-08AYM6) if higher current capacity is acceptable. Direct replacements must maintain the SOT-23-6 package and 2.5V-5.5V operating range. Verify that any alternative part supports the same active-high or active-low enable logic and fault flag configuration.
