MCP73864T-I/SL

Overview

The MCP73864T-I/SL is a highly integrated single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It features an internal power switch to minimize external component count and board space. The device provides system load sharing, allowing the input source to supply both the charger and the system load simultaneously. It includes thermal regulation to manage charging current based on die temperature, ensuring reliability under high-power conditions.

Feature Summary

• Integrated linear charge management with internal power switch for compact design
• System load sharing capability to support simultaneous charging and operation
• On-chip thermal regulation to reduce charging cycle time and maintain safety
• Charge status indication via dedicated output pin

Applications

• Portable consumer electronics requiring small form factor battery charging
• Handheld devices with limited PCB space constraints
• Applications requiring simultaneous system operation during charging
• Battery-powered equipment needing simplified bill of materials

Procurement Notes

Verify the specific suffix 'I/SL' against the official Microchip datasheet to confirm the industrial temperature range and SOIC-8 package variant. Confirm end-of-life status as distribution channels may list discontinued inventory. Ensure compatibility with existing PCB footprint and reflow profiles before procurement.

Selection Notes

Select this component when a fully integrated solution with an internal switch is required to save board area. It is suitable for applications where the input voltage exceeds the battery voltage and thermal management is critical. Compare with the MCP73861 series if different pinouts or specific feature sets are needed for the same application class.

Part Context

This part belongs to the MCP7386X family of charge management controllers designed for space-limited applications. The family shares common architecture but varies in package type and specific electrical characteristics. The MCP73864T-I/SL specifically utilizes the SOIC-8 package, distinguishing it from MSOP or TSSOP variants within the same functional family.

Replacement Considerations

Direct substitutes include other MCP7386X variants such as MCP73861T-I/SL, provided the pinout and package dimensions match the existing design. Verify that the replacement maintains the same thermal regulation behavior and load sharing capabilities.
