MCP73841-410I/UN

Overview

The MCP73841-410I/UN is a linear charge management controller designed for single-cell lithium-ion and lithium-polymer batteries. It features a fixed 4.1V output voltage regulation with high accuracy. The device supports programmable charge current and includes automatic end-of-charge control, cell preconditioning, and safety timers. It operates within a supply voltage range of 4.5V to 12V and functions in temperatures from -40°C to +85°C. The component is housed in a 10-pin MSOP package.

Feature Summary

Integrates constant-voltage and constant-current regulation with automatic charge termination
Includes advanced safety timers and cell temperature monitoring capabilities
Provides charge status indication for direct LED drive
Supports preconditioning of deeply depleted cells

Applications

Lithium-Ion/Lithium-Polymer battery chargers
Cellular telephones
Personal data assistants
Hand-held instruments
Digital cameras

Procurement Notes

Verify the specific suffix 'I/UN' against the manufacturer datasheet to confirm the industrial temperature range and tube packaging format. Ensure compatibility with the required 4.1V preset output voltage for the target battery chemistry. Cross-reference the 10-pin MSOP footprint dimensions during PCB layout to prevent assembly errors.

Selection Notes

Select this model when a fixed 4.1V charging profile is required for specific lithium-ion or polymer cells. The 10-pin MSOP package offers space efficiency for portable devices. Consider the integrated temperature monitoring if thermal safety is critical. Verify that the input voltage range covers the system's power source variations.

Part Context

This component belongs to the MCP7384X family of advanced charge management controllers by Microchip Technology. The family provides complete stand-alone solutions for portable applications. The MCP73841 variant specifically targets single-cell configurations with fixed voltage options, distinguishing it from dual-cell models in the same series.
