Procurement Notes
Verify the specific suffix 'QP' against the official Microchip datasheet to confirm automotive qualification status and any associated reliability standards. Confirm the active lifecycle status directly with the manufacturer, as availability may vary. Ensure the VQFN-40 package dimensions match your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when a multi-channel solution is required for synchronized LED driving. The closed-loop design offers superior accuracy compared to open-loop alternatives. Consider the 10 V to 40 V input range compatibility with your system power supply. Evaluate the thermal performance of the VQFN-40 package under maximum load conditions.
Part Context
This part belongs to the HV9985 series from Microchip Technology, which focuses on LED lighting drivers. The series includes variants such as the HV9985K6-G and HV9986K6-G. These devices are categorized under LED Lighting Drivers and Driver ICs, targeting applications requiring precise current control for multiple LED outputs.
Replacement Considerations
The HV9985K6-G is a related variant within the same family. Verify if the pinout and electrical specifications are identical before substitution. Cross-reference the specific suffix differences in the official datasheet to ensure functional equivalence.
