Overview
The MIC2039BYM6-TR is a high-side power distribution switch manufactured by Microchip Technology. It features an adjustable current limit ranging from 200 mA to 2.5 A and a maximum on-resistance of 125 mΩ. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum output current of 350 mA. It includes protection against over-temperature conditions with a shutdown feature. The component is housed in a SOT-23-6 surface-mount package and functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Adjustable current limiting capability for customizable load protection
- Integrated thermal shutdown to prevent damage during overheating events
- Controlled slew rate to minimize inrush current during turn-on
Applications
- Power distribution in embedded systems requiring high-side switching
- Load protection circuits in industrial control applications
- Peripheral power management in consumer electronics devices
Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm RoHS compliance status through official manufacturer documentation before integration. Check for recent Product Change Notifications (PCNs) regarding manufacturing site or material changes. Ensure compatibility with existing PCB footprint and soldering profiles for the SOT-23-6 package.
Selection Notes
Select this component when adjustable current limiting is required rather than fixed threshold protection. Consider the 125 mΩ on-resistance for power dissipation calculations at expected load currents. Verify that the 2.5 V minimum supply voltage aligns with system logic levels. Evaluate the need for thermal management given the +125°C junction temperature rating.
Part Context
This part belongs to the MIC2039 family of high-side power switches designed for robust load protection. It serves as a replacement for legacy Micrel products following the company's acquisition by Microchip Technology. The series offers configurable current limits and integrated safety features for modern power distribution needs.
Replacement Considerations
MIC2039AYM6-TR: Features lower on-resistance (75 mΩ typical) but may have different current limit ranges. MIC2039EYM6-TR: Previously available variant; verify current availability and exact electrical parameter alignment before substitution.
