Procurement Notes
Verify component authenticity through official onsemi channels or authorized distributors. Confirm the specific suffix matches project requirements. Check for End-of-Life status as indicated by historical records. Ensure compliance with RoHS standards before integration into final assemblies.
Selection Notes
Select this component when a compact footprint is required for multi-channel LED driving. Evaluate thermal performance within the small TQFN package. Consider the input voltage range compatibility with system power rails. Assess the need for fractional dimming capabilities versus standard PWM options.
Part Context
This part belongs to the CAT3636 series of LED drivers. It shares architectural similarities with other models in the family but offers specific channel counts and packaging options. The series targets portable electronics where space and efficiency are critical constraints.
Replacement Considerations
Direct substitutes may include CAT3636HV3-GT2 or CAT3637HV3-GT2. Verify pinout compatibility and electrical specifications before substitution. Consult official obsolescence notices for availability changes.
