Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details directly with the manufacturer or distributor documentation. Ensure the specific suffix matches project requirements as ordering variations may exist. Cross-reference datasheet revisions to validate electrical characteristics against current design specifications before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring a dedicated linear charger solution for single-cell lithium batteries. Evaluate thermal performance based on the 1.25 W power dissipation limit in the QFN-8 package. Verify that the input voltage range of 3.3 V to 10.4 V aligns with the system power source. Consider the 1.5 A output current capability relative to the target battery capacity and charging time requirements.

Part Context

This part belongs to the MP2678 series of battery management ICs from Monolithic Power Systems. It is categorized under PMIC - Power Management ICs specifically for charge management. The component is distinct from switching regulators like the MP28119 or other battery chargers such as the MP2618EV-LF-Z which feature different pin counts and voltage ranges.
