LED Driver IC Procurement Notes

Verify the specific suffix designation carefully, as package variations exist within the family. Confirm availability status directly with authorized distributors due to potential supply constraints. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when designing circuits requiring four isolated LED channels with high input voltage tolerance. Consider the TSSOP-20 package for space-constrained PCB layouts. Evaluate the need for AEC-Q100 compliance if deploying in automotive environments. Compare against linear driver alternatives if lower voltage drops are acceptable for improved efficiency.

LED Driver IC Part Context

This part belongs to the MAX16813 series of integrated LED drivers. It shares functional similarities with other Maxim Integrated PMIC solutions but is distinct in its four-channel architecture and specific topology support. The series targets applications demanding reliable, high-current LED regulation without external MOSFETs.

LED Driver IC Replacement Considerations

Direct substitutes include MAX16813ATP+ and MAX16813BAUP/V+T. Verify pin compatibility and package dimensions (TSSOP vs TQFN) before substitution. Ensure equivalent electrical ratings and feature sets match the original design requirements.
