- Portable computer peripheral power distribution
Procurement Notes
Verify the exact suffix against official Microchip documentation to confirm package type and temperature range. Ensure the source provides valid traceability for original components. Cross-reference the part number with authorized distributors to avoid counterfeit inventory. Confirm surface-mount compatibility with your PCB design constraints before procurement.
Selection Notes
Select this component when designing systems requiring dedicated power control for single-slot PC Card or CardBus interfaces. It is suitable for applications needing integrated switching and protection without external discrete components. Consider the 14-SOIC footprint during layout planning. Verify thermal performance within the specified operating temperature range for your specific enclosure environment.
Part Context
This part belongs to the Microchip Technology MIC2566 family of power management ICs. These controllers are specialized for legacy expansion bus standards. The series includes variants with different packaging options such as TSSOP. They address the power sequencing needs of mobile computing devices adhering to PCMCIA and CardBus industry standards.
Replacement Considerations
Check for MIC2566-1BTS as a potential alternative if TSSOP packaging is required instead of SOIC. Verify pinout compatibility before substitution. Ensure the replacement supports the same 3.3V/5V input requirements and current ratings for your specific slot design.
