Overview
The MIC2073-2YM is a dual-channel high-side power distribution switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and features an 8-SOIC package. The device provides two independent outputs with a maximum output current of 500 mA per channel and a fixed current limit of 900 mA. It includes integrated protection against overcurrent, overtemperature, and under-voltage lockout conditions.
Feature Summary
- Dual-channel high-side switching architecture for independent load control
- Integrated fault protection including fixed current limiting and thermal shutdown
- Controlled slew rate functionality to minimize inrush current during activation
Applications
- USB port power distribution and protection
- Peripheral device power switching in consumer electronics
- General-purpose high-side load management in industrial systems
Procurement Notes
Verify the specific suffix and tape/reel configuration when ordering to ensure compatibility with automated assembly processes. Confirm that the 8-SOIC package dimensions align with the target PCB footprint. Check moisture sensitivity level requirements if the component has been stored outside its specified environmental conditions prior to soldering.
Selection Notes
Select this component when dual-channel isolation is required within a compact surface-mount form factor. The 500 mA continuous output capability suits standard peripheral loads. Ensure the system design accommodates the thermal dissipation requirements associated with the SOIC-8 package under maximum load conditions.
Part Context
This part belongs to the MIC207x series of USB power switches designed for robust power distribution. It succeeds earlier Micrel designs acquired by Microchip, maintaining pin-out compatibility while offering enhanced reliability. The device serves as a critical interface between host power sources and downstream peripherals.
Replacement Considerations
MIC2073-2YM-TR is the reel-packaged equivalent. MIC2074-2YM offers similar dual-channel functionality with potentially different electrical characteristics. Verify pin compatibility and parameter alignment before substituting.
