MCP73833-FCI/MF

Overview

The MCP73833-FCI/MF is a standalone linear charge management controller designed for single-cell lithium-ion and lithium-polymer batteries. It operates within an input voltage range of 3.75 V to 6 V and supports a maximum output current of 1.2 A, with a regulated charging voltage of 4.2 V. The device is housed in a DFN package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates complete charge management control logic for safe lithium battery charging
• Includes thermal regulation to reduce charging rate during high temperature conditions
• Provides status indication via dedicated output pin

Applications

• Single-cell lithium-ion battery charging systems
• Lithium-polymer battery power management modules
• Portable electronic devices requiring compact charge controllers

Procurement Notes

Verify the specific suffix 'FCI' against official Microchip documentation to confirm exact marking and packaging details. Ensure compatibility with required thermal dissipation methods given the DFN package type. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a compact solution for single-cell Li-Ion or Li-Po charging is required. The DFN package offers thermal advantages over standard plastic packages. Verify that the system input voltage remains within the specified 3.75 V to 6 V range to ensure proper operation and protection features remain active.

Part Context

This part belongs to the MCP7383x family of charge management controllers from Microchip Technology. The series provides integrated solutions for single-cell lithium batteries, combining constant-current and constant-voltage charging profiles with safety features like thermal regulation and charge termination detection.

Replacement Considerations

The MCP73833T-FCI/MF serves as the tape-and-reel variant of this component. Other members of the MCP7383x family may offer similar functionality but require verification of package dimensions and electrical parameters.
