Overview
The MIC2033-05BYM6-TR is a high-side power distribution switch from Microchip Technology, designed for system reliability. It features a 5% current limit accuracy and operates within an input voltage range of 2.5V to 5.5V. The device provides a fixed current limit of 500mA with a maximum output current of 350mA. Key electrical parameters include a maximum on-resistance of 177mΩ, a maximum turn-on time of 700µs, and a maximum off-time of 5µs. It functions across a junction temperature range of -40°C to +125°C.
Feature Summary
- High-accuracy ±5% current limit ensures precise load protection.
- Integrated thermal shutdown protects the device and system from overheating.
- Open drain fault status output flag indicates over-current or thermal events.
Applications
- Power distribution in embedded systems
- Load switching for high-capacitive loads
- System reliability enhancement in industrial applications
Procurement Notes
Verify the specific suffix BYM6 corresponds to the SOT-23-6 package and active-high logic configuration as documented in the official datasheet. Confirm that the ordering part number matches the required current limit option of 0.5A. Ensure compatibility with the specified operating voltage range of 2.5V to 5.5V for the target application design.
Selection Notes
Select this component when high-side switching with precise current limiting is required. The 5% accuracy distinguishes it from standard switches. Consider the soft-start capability via external capacitor if inrush current management is critical. Verify that the 177mΩ maximum on-resistance meets the efficiency requirements of the power rail.
Part Context
The MIC2033 series comprises high-side MOSFET power distribution switches offering increased system reliability. This model belongs to the family featuring fixed current limit options including 0.5A, 0.8A, 1A, and 1.2A. It utilizes internal current limiting and thermal shutdown mechanisms. The series supports both active-high and active-low enable inputs and is available in SOT-23 and DFN packages.

FAQ
How does the MIC2033-05BYM6-TR handle short-circuit conditions?
It employs fast response time (10µs) to short-circuit loads and asserts a low fault status flag during over-current conditions while limiting the current to the specified 500mA.
What is the purpose of the fault status output flag?
The open drain fault status output flag asserts low during over-current or thermal shutdown conditions, providing a built-in 32ms delay to indicate faults.
