Procurement Notes
Verify product status as obsolete or end-of-life before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing design specifications regarding package type and electrical parameters. Check for alternative components if long-term supply stability is required.
Selection Notes
Select this component for applications requiring a simple, low-current solution for single-cell lithium-ion batteries. Consider the 300 mA output limit when sizing for battery capacity and charge time requirements. Evaluate the DFN-10 package constraints for PCB layout and thermal management. Verify that the 4.2 V regulation matches the specific battery cell chemistry requirements.
Part Context
This part belongs to the NCP1835 series of battery chargers from onsemi. The series includes variants such as the NCP1835MN24R2G, which offers higher current capabilities. These devices are categorized under PMIC - Battery Chargers and are designed for efficient power management in portable applications.
Replacement Considerations
Check for direct pin-compatible substitutes within the NCP1835 family, such as the NCP1835MN24R2G, noting differences in output current ratings. Verify functional equivalence for single-cell lithium-ion charging applications.
