Procurement Notes

Verify the component meets AEC-Q100 qualification standards for automotive reliability. Confirm the specific suffix matches the required packaging format. Ensure compatibility with the host controller's daisy chain protocol. Check that the operating temperature range aligns with the intended vehicle environment. Validate pinout configurations against the official datasheet before implementation.

Selection Notes

Select this model when designing automotive displays requiring localized brightness control. Choose based on the need for 16-channel precision without external MOSFETs. Consider the WQFN-24 footprint for space-constrained PCB layouts. Evaluate the 60 mA sink capacity against the target LED array specifications. Ensure the input voltage range suits the vehicle's power architecture.
