NCV78763DQ0CR2G

Overview

The NCV78763DQ0CR2G is an automotive-grade single-chip power ballast and dual LED driver designed for high-current applications. It features two independent buck switch channels capable of driving LED strings up to 60V with a DC output current of 1.6A per channel. The device integrates a current-mode voltage boost controller for input current filtering, reducing external component count. Operating within a supply voltage range of 4V to 40V at a switching frequency of 8MHz, it supports PWM dimming and includes short circuit and thermal protection. Qualified under AEC-Q100 standards, it operates between -40°C and +150°C in an SSOP-36 package.

Feature Summary

• Integrates dual independent buck channels and a boost controller for comprehensive LED drive solutions
• Supports high-voltage LED strings up to 60V with integrated diagnostic capabilities
• Features SPI programmability for flexible system configuration and multi-phase operation

Applications

• Automotive headlight systems including high beam and low beam
• Daytime Running Lights (DRL) and fog lights
• Turn signal indicators and static cornering lights

Procurement Notes

Verify the specific suffix DQ0C against official onsemi documentation to confirm pinout and electrical characteristics, as variations exist within the NCV78763 family. Ensure compatibility with the target SSOP-36 footprint and validate that the AEC-Q100 qualification meets your project's reliability requirements. Cross-reference the datasheet revision date to ensure access to the latest technical specifications and application notes.

Selection Notes

Select this component when designing high-power automotive lighting requiring integrated boost and buck regulation in a single package. It is suitable for applications needing precise current control for multiple LED strings with minimal external passive components. Consider its SPI interface if dynamic configuration or multi-device synchronization is required for complex lighting architectures.

Part Context

This part belongs to the NCV78763 series of intelligent power ballasts and LED drivers from onsemi. It is engineered specifically for next-generation automotive lighting platforms, offering a compact solution for high-efficiency illumination. The series supports scalable designs by allowing multiple devices to be combined for higher channel counts while maintaining synchronized operation through shared control interfaces.

Replacement Considerations

Consult official substitution guides for variants such as NCV78763MW0R2G or NCV78763DQ9R2G. Verify package compatibility and electrical parameter alignment before replacing. Note that different suffixes may indicate distinct packaging options or minor functional differences requiring schematic review.
