Overview
The MCP73862-I/SL is a fully integrated charge management controller designed for dual-cell lithium-ion or lithium-polymer battery packs. It supports input voltages up to 14V and provides regulated charging currents up to 2A per cell. The device implements standard CC/CV charging profiles with termination logic, thermal regulation, and safety timers. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 16-lead SOIC package.
Feature Summary
- Fully integrated control for dual-cell Li-Ion/Li-Po batteries
- Supports high input voltage up to 14V
- Includes thermal regulation and safety timer features
Applications
- Dual-cell portable electronic devices
- Industrial equipment battery packs
- Medical device power systems
Procurement Notes
Verify the specific suffix 'I/SL' against official Microchip documentation to confirm the industrial temperature grade and SOIC package variant. Confirm current manufacturing status as availability may vary. Ensure compatibility with existing PCB footprints and design-in requirements before procurement.
Selection Notes
Select this component for applications requiring independent or combined charging of two series-connected cells. Verify that the required charging current does not exceed the 2A limit per cell. Ensure the system input voltage remains within the 14V maximum rating. Consider the SOIC package constraints for thermal dissipation in enclosed designs.
Part Context
This part belongs to Microchip's MCP7386x family of advanced charge controllers. It is specifically engineered for dual-cell configurations, distinguishing it from single-cell variants like the MCP73861. The device integrates protection features typically found in discrete solutions, simplifying the bill of materials for dual-cell battery management systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Microchip technical support for verified alternatives if this obsolete component requires replacement.
