Procurement Notes

Verify the specific suffix and package variant when ordering, as Richtek may offer different thermal or electrical variants within the RT9468 family. Confirm I2C address configuration and programming requirements during design-in. Ensure compatibility with host controller voltage levels, particularly regarding the 1.8V logic reference mentioned in technical documentation. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly processes.

Selection Notes

Select this component when a compact, fully integrated single-cell charger with programmable I2C control is required. It is suitable for designs prioritizing small PCB footprint due to the 4x4mm QFN package. Consider its power path management features if simultaneous charging and system operation are needed. Verify that the target application does not exceed the thermal limits defined for the -40°C to 85°C operating range.
