Procurement Notes

Verify the specific suffix 'I/SL' corresponds to the industrial temperature range and tape-and-reel packaging configuration. Confirm that the 16-lead SOIC package matches your PCB footprint requirements. Ensure compatibility with the 4.1V target voltage for your specific cell chemistry. Check for any recent lifecycle notices regarding this specific part number variant.

Selection Notes

Select this component when a highly integrated solution for single-cell charging and load switching is required. It is suitable for applications where minimizing external component count is critical. Consider the 10mA output current limit and 12V maximum input voltage when designing the power stage. Verify that the 16-SOIC package is compatible with your assembly process.

Part Context

This part belongs to the MCP7386x family of charge management controllers from Microchip Technology. The family includes variants like the MCP73861, MCP73862, and MCP73864, which offer different pin counts or dual-cell capabilities. The MCP73863 specifically targets single-cell applications with a 16-lead SOIC package, providing a balance between integration and pin availability.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the MCP7386x family, such as the MCP73861 or MCP73862, if pinout compatibility allows. Verify electrical specifications against alternative single-cell chargers from Microchip or other manufacturers.
