Procurement Notes

Verify the component status carefully as this part number is listed as obsolete or discontinued. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the specific suffix matches the required package and tape/reel specifications. Check RoHS compliance status against project requirements, as older revisions may not meet current environmental standards. Validate lead times and minimum order quantities with suppliers before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a dedicated single-cell Li-ion charger with a 1A current limit. Ensure the input supply voltage does not exceed the 16V maximum rating. Verify that the 8-MSOP package footprint aligns with the PCB layout constraints. Consider the operating temperature range suitability for the intended environment. Evaluate if the built-in overvoltage protection meets the system safety requirements without additional external circuitry.

Part Context

This IC belongs to the NCP1800 series of battery chargers from onsemi. It is designed specifically for managing the charge cycle of single-cell lithium-ion batteries. The device integrates essential charging algorithms and protection features into a small form factor, simplifying the design of portable battery-powered products.
