Overview
The LA9932UVD-XE is a dual-channel LED driver IC designed for automotive exterior lighting applications, specifically tail lamps and brake lights. It integrates two constant-current sinks capable of driving high-power LEDs with precise current regulation. The device features an I²C interface for digital control of brightness levels and operational modes. It includes comprehensive protection mechanisms such as open-load detection, short-to-ground protection, and thermal shutdown to ensure reliability under harsh automotive conditions. The component operates within a wide supply voltage range suitable for 12V and 24V automotive electrical systems.
Feature Summary
- Dual-channel constant-current sink architecture for independent LED control
- I²C digital interface for programmable brightness and diagnostic feedback
- Integrated fault detection including open-load and short-circuit monitoring
- Automotive-grade reliability with extended temperature operation capabilities
Applications
- Automotive tail lamp modules
- Brake light assemblies
- Rear combination lighting units
- LED-based exterior vehicle illumination systems
Procurement Notes
Verify the specific suffix 'XE' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with automotive qualification standards required for your application. Confirm that the I²C address configuration matches your system design. Check for any recent lifecycle status changes or recommended new parts from onsemi before finalizing procurement.
Selection Notes
Select this component when designing automotive exterior lighting requiring precise dual-channel current control via digital interface. It is suitable for applications needing integrated diagnostics and robust fault protection in a compact package. Consider thermal management requirements based on the expected LED load and ambient operating temperatures. Verify that the I²C bus speed and addressing scheme align with the main controller in the vehicle network.
Part Context
This part belongs to onsemi's portfolio of automotive LED drivers, which are engineered to meet stringent AEC-Q100 reliability standards. These devices support the industry shift towards solid-state lighting in vehicles by offering high efficiency and advanced diagnostic features. The LA9932 series is specifically tailored for rear lighting applications where safety and visibility are critical.
Replacement Considerations
Consult onsemi's official cross-reference documentation for direct pin-compatible replacements. Verify that any substitute part maintains the same I²C command set and current sink characteristics to avoid redesigning the PCB or firmware.
