Overview
The ASL3417SHNY is a three-channel buck mode LED driver IC from NXP Semiconductors, designed for automotive applications. It delivers constant average DC current to LEDs independent of input voltage variations. Key specifications include an output current of 1.5 A per channel, a supply voltage range from 10 V to 80 V, and a 32-HVQFN (5x5) package. The device supports SPI communication and features PWM dimming capabilities with individual channel control.
Feature Summary
- Three-channel buck mode architecture delivering constant average DC current
- Integrated Limp-home mode for enhanced system reliability
- Independent PWM dimming control for each channel via SPI interface
Applications
- Automotive exterior lighting systems
- LED headlamp driver circuits
- Vehicle ambient lighting modules
Procurement Notes
Verify the specific suffix 'Y' against official NXP documentation to confirm tape-and-reel packaging configuration. Ensure the component meets AEC-Q100 automotive grade requirements for your target environment. Cross-reference the 32-HVQFN footprint with your PCB layout guidelines before finalizing procurement orders.
Selection Notes
Select this component when designing automotive LED drivers requiring independent channel control and high input voltage tolerance up to 80 V. The integrated limp-home feature makes it suitable for safety-critical lighting applications where fault tolerance is essential. Ensure the design accommodates the thermal requirements of the HVQFN package under maximum load conditions.
Part Context
This part belongs to NXP's ASL series of automotive-grade LED drivers. It shares functional similarities with the ASL3416SHN but offers specific enhancements for buck-mode operation. The series is engineered to provide robust performance in vehicle environments, supporting complex lighting architectures through standardized digital interfaces.
Replacement Considerations
The ASL3416SHN is a related three-channel variant within the same family. Verify pin compatibility and electrical parameter alignment before substitution. No other direct substitute part numbers are confirmed in public documentation.
