Procurement Notes
Verify the complete part number including suffixes such as R2G to ensure correct packaging and tape specifications. Confirm that the specific variant matches the required SOIC-8 package and AEC-Q100 automotive qualification. Cross-reference the datasheet revision to validate electrical parameters against the intended application requirements before finalizing procurement orders.
Selection Notes
Select this component when a single-channel driver with combined Boost/Buck capability is required for automotive LED applications. Ensure the input voltage range aligns with the system's 4.5 V to 18 V operating window. Consider the 25 mA output current limit and 100 kHz switching frequency for compatibility with the target LED load and thermal management design constraints.
Part Context
This part belongs to the NCV7691 series of LED current controllers specifically engineered for automotive environments. It serves as a dedicated pre-driver solution for managing individual LED channels in complex lighting architectures. The series emphasizes reliability and compliance with strict automotive industry standards for electronic components.
Replacement Considerations
Consult official onsemi documentation for direct cross-references or updated revisions within the NCV7691 family. Verify pinout and electrical parameter compatibility if considering alternative single-channel LED drivers from other manufacturers.
