• Programmable constant-current and constant-voltage charging profiles
• Internal thermal regulation to reduce external component count
• Input current limiting for USB compliance

Applications

• Smartphones and mobile phones
• Tablets and handheld computers
• Portable media players
• Digital cameras

Procurement Notes

Verify the specific suffix (LF-Z) against the manufacturer's latest datasheet to confirm lead-free status and RoHS compliance. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference with official distributor catalogs to confirm current availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a compact, single-cell Li-Ion/Polymer charging solution with integrated power path management. It is suitable for designs where minimizing external components and simplifying thermal management are priorities. Consider its input voltage range and maximum current capabilities relative to the host system's power supply constraints.

Part Context

This part belongs to the MP267x series of battery chargers from Monolithic Power Systems. It is designed as a drop-in replacement or alternative for other single-cell charger ICs in consumer electronics. The device integrates most functions typically requiring discrete components, offering a space-efficient solution for modern portable devices.

Replacement Considerations

Check pin-to-pin compatibility with existing designs if replacing older MP267x variants. Verify that the new version's thermal characteristics and protection thresholds meet the original design specifications. Consult MPS documentation for any recommended layout changes when transitioning between different revisions.
