Overview
The ASL5115SHV/0Y is a Matrix LED Controller (MLC) from NXP Semiconductors, designed for automotive applications. It features a switched capacitor (charge pump) topology with PWM dimming capability and supports up to 12 output channels. The device operates within a supply voltage range of 4.5V to 5.5V and delivers an output current of 1.5A per channel. It is housed in a 48-HLQFP package with exposed pad and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a switched capacitor charge pump topology for efficient power conversion
- Supports high-frequency PWM dimming for precise LED brightness control
- Provides twelve independent output channels for matrix LED configurations
Applications
- Automotive exterior lighting systems
- Matrix LED headlamp modules
- Advanced driving assistance system (ADAS) illumination components
Procurement Notes
Verify the specific suffix '0Y' against the manufacturer's official documentation to confirm packaging details and tape-and-reel specifications. Ensure compatibility with the required 48-HLQFP footprint during PCB design. Cross-reference the component grade as automotive-grade to meet environmental reliability standards for vehicle integration.
Selection Notes
Select this component when designing automotive matrix LED systems requiring integrated charge pump functionality and multi-channel control. The 48-pin HLQFP package suits space-constrained designs needing robust thermal performance. Confirm that the 1.5A per-channel current rating aligns with the target LED array specifications and that the 4.5V to 5.5V supply range matches the vehicle's electrical architecture.
Part Context
This part belongs to the ASL5xxxyHz family of Matrix LED Controllers, which are engineered for flexible and cost-effective automotive lighting solutions. The series integrates advanced control features tailored for modern vehicle lighting requirements, emphasizing reliability and precise dimming capabilities in harsh operating environments.
Replacement Considerations
The ASL5115FHNZ is a documented alternative within the same family, offering identical functional specifications but utilizing a 36-HVQFN package instead of the 48-HLQFP form factor. Verify pinout compatibility and thermal management requirements before substitution.
