Procurement Notes
Verify the specific suffix 'BML' against official Microchip documentation to confirm package type and availability status. Ensure compatibility with system voltage requirements not exceeding 16V. Confirm thermal performance meets application needs given the 125°C junction temperature limit. Cross-reference datasheet revisions for any changes in pinout or electrical characteristics prior to integration.
Selection Notes
Select this component for applications requiring a single-cell Li-ion charger with built-in safety protections. The 1.2A max charge current suits moderate-power portable devices. Consider the 10-MLF package for PCB space efficiency. Verify that the input voltage source remains within the 16V maximum rating. Evaluate thermal dissipation capabilities in the final enclosure design.
Part Context
This part belongs to the MIC79110 series of battery chargers from Microchip Technology. It is specifically configured for single-cell lithium-ion applications. The series offers integrated power path management and safety features. The BML suffix indicates a specific tape-and-reel packaging variant for automated assembly processes.
