Overview
The MCP73844T-840I/MS is a charge management controller designed for lithium-ion and lithium polymer batteries. It provides an output voltage of 8.4 V with a maximum output current of 10 mA. The device operates on a supply voltage ranging from 8.7 V to 12 V. It is housed in an MSOP-8 package and supports surface mount installation. This component includes a charge safety timer feature.
Feature Summary
- Integrated charge safety timer for enhanced battery protection
- Compatible with single-cell lithium-ion and lithium polymer chemistries
Applications
- Portable electronic devices requiring safe charging protocols
- Battery-powered equipment utilizing dual-series cell configurations
- Consumer electronics with limited space constraints
Procurement Notes
Verify the active status of this component, as official records indicate it may be obsolete or subject to discontinuation. Confirm the specific suffix 'T' denotes tape and reel packaging if required for automated assembly. Ensure compatibility with the 8.4 V target voltage for your specific battery stack before procurement.
Selection Notes
Select this part when designing systems that require precise termination at 8.4 V for two series-connected cells. The low 10 mA output current limits its use to small-capacity batteries or trickle charging applications. Verify that the input supply voltage remains within the 8.7 V to 12 V operational range for proper regulation.
Part Context
This component belongs to the MCP7384x family of battery chargers from Microchip Technology. It shares functional similarities with other parts in the series but is distinguished by its specific 8.4 V output configuration and integrated safety timer. It serves as a specialized solution for dual-cell lithium battery management.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating other members of the MCP7384x family, such as the MCP73843T-410I/MS, while accounting for differences in output voltage and package type.
