Overview
The MIC2039EYMT-TR is an adjustable high-side power distribution switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum output current of 350 mA. The device features an adjustable current limit ranging from 200 mA to 2.5 A, with a maximum on-resistance of 177 mOhms. It includes protection mechanisms such as thermal shutdown and under-voltage lockout. 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 precise load protection
- Integrated thermal shutdown and under-voltage lockout for system safety
- High-side switching topology suitable for power distribution applications
Applications
- Power distribution networks requiring adjustable current limits
- Hot insertion scenarios for peripheral devices
- Battery-powered systems needing efficient power management
Procurement Notes
Verify the specific suffix EYMT against official Microchip documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint and thermal requirements. Cross-reference datasheet revisions to confirm RoHS compliance status and manufacturing origin details before finalizing procurement orders.
Selection Notes
Select this component when adjustable current limiting is required rather than fixed thresholds. Consider the 177 mOhms on-resistance for power dissipation calculations. Verify that the 2.5 V minimum supply voltage aligns with the system's available rail. Evaluate the SOT-23-6 package size constraints against board space limitations.
Part Context
This part belongs to the MIC2039 family of high-side power switches designed for robust load protection. It serves as a critical interface between power sources and sensitive loads, offering configurable protection parameters. The series is widely used in industrial and consumer electronics where reliable power sequencing and fault isolation are essential.
Replacement Considerations
Check for MIC2039AYM6-TR or MIC2039BYM6-TR if different current limit ranges or resistance values are acceptable. Verify pin-to-pin compatibility before substitution.
