• General industrial LED illumination

LED Driver IC Procurement Notes

Verify the specific suffix (e.g., +T) against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm AEC-Q100 automotive qualification status if required for your application. Check current supply availability as distribution may be limited or subject to factory order constraints.

LED Driver IC Selection Notes

Select this component when designing circuits requiring multiple LED strings driven by a single controller with integrated power management. Ensure the design accommodates the 4.75V to 40V input range and utilizes the appropriate external inductor and MOSFETs for the chosen topology. Verify thermal performance for the TSSOP-20 package under maximum load conditions.

LED Driver IC Part Context

This part belongs to the MAX16814 family of high-brightness LED drivers manufactured by Analog Devices/Maxim Integrated. It is designed to replace discrete solutions by integrating both the linear current sinks and the switching regulator controller into a single compact package, simplifying board layout and reducing component count for multi-string LED applications.

LED Driver IC Replacement Considerations

Consult official substitution guides for compatible variants within the MAX16814 series, such as the MAX16814CUP+T or MAX16814BUP+T, ensuring pinout and electrical parameter compatibility before implementation.
