Overview
The MCP73861-I/MLG is a single-cell lithium-ion or lithium-polymer battery charge management controller manufactured by Microchip Technology. It integrates linear charging, system load distribution, and battery status indication functions into a compact 16-pin QFN package. Designed for space-limited applications, the device supports input voltages from 2.3 V to 5.5 V and operates within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates linear charge management with system load path management for efficient power distribution
- Provides accurate constant-current and constant-voltage charging profiles for single-cell Li-ion/Polymer batteries
- Includes integrated thermal regulation to manage die temperature during high-current charging operations
Applications
- Portable consumer electronics requiring compact battery solutions
- Medical devices with strict space and safety constraints
- Industrial handheld instruments and IoT edge nodes
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 16-lead QFN configuration. Cross-reference datasheet revisions to validate pinout consistency before finalizing procurement orders.
Selection Notes
Select this component when a highly integrated solution is required for single-cell lithium-based chemistries. It is suitable for designs where minimizing external component count and board area is critical. Verify that the application's input voltage source aligns with the specified operating range.
Part Context
This part belongs to the MCP73xx series of charge management controllers from Microchip Technology. The series is characterized by high integration levels designed to reduce bill-of-materials complexity in portable electronic devices. The I/MLG designation indicates the industrial temperature grade and the specific MLG package variant.
Replacement Considerations
Consult official Microchip substitution guides for verified alternatives. Generic equivalents may lack identical thermal regulation or load path features.
