NCV7684DQR2G

Overview

The NCV7684DQR2G is a 12-channel LED lighting driver IC designed for automotive applications. It features an I2C interface for control and supports PWM output topology. The device delivers a maximum output current of 60 mA per channel with a supply voltage range from 5 V to 28 V. Operating frequencies reach up to 500 Hz, and it functions within a temperature range of -40°C to +150°C. Packaged in an SSOP-EP-24 format, it holds AEC-Q100 qualification.

Feature Summary

• Provides twelve independent constant current channels for LED driving
• Enables digital configuration via standard I2C communication interface
• Supports PWM dimming topology for precise light intensity control
• Engineered for high-temperature operation suitable for automotive environments

Applications

• Automotive exterior lighting systems
• Interior cabin illumination arrays
• Dashboard and instrument cluster backlighting
• Signaling and indicator LED modules

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix matches the required package and tape/reel specifications. Check for obsolescence status as indicated by lifecycle notices. Ensure ESD handling protocols are followed during storage and assembly. Validate that the operating conditions align with the specified electrical limits.

Selection Notes

Select this component when twelve individually controllable LED channels are required. Choose based on the need for I2C programmability over parallel GPIO usage. Consider the 60 mA output capability relative to load requirements. Evaluate the 28 V maximum supply voltage against system power rails. Assess thermal management needs given the extended temperature range capabilities.

Part Context

This part belongs to the NCV7684 series of LED drivers from onsemi. It shares functional similarities with other multi-channel drivers but is distinct in its twelve-channel count and specific I2C implementation. It complements broader automotive lighting portfolios by offering integrated control and drive capabilities in a compact surface-mount package.

Replacement Considerations

Consult official substitution guides for direct equivalents. Verify pin compatibility and electrical parameters before swapping. Cross-reference with similar models like NCV7683 if channel count differs. Ensure regulatory compliance remains intact after replacement.
