ASL5008FHNZ

Overview

The ASL5008FHNZ is a 12-channel LED lighting driver IC manufactured by NXP Semiconductors. It utilizes a PWM topology and operates within an output current range of 800 mA. The component is housed in a 36-HVQFN package with an exposed pad, designed for surface mount installation. It supports a wide operating temperature range from -40°C to +125°C. The device integrates a switched capacitor charge pump architecture for efficient power management in LED applications.

Feature Summary

• Integrates twelve independent output channels for multi-zone LED control
• Employs pulse-width modulation (PWM) dimming technology for precise brightness regulation
• Incorporates an internal switched capacitor charge pump for voltage conversion
• Designed for high-temperature operation suitable for automotive environments

Applications

• Automotive exterior lighting systems
• Interior ambient LED illumination
• Multi-zone LED matrix drivers
• High-density LED backlighting arrays

Procurement Notes

Verify the specific suffix 'FHNZ' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering quantity aligns with the factory reel packaging requirements specified in the product documentation. Confirm that the 36-VFQFN package dimensions match the target PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring simultaneous control of multiple LED strings without external multiplexing. The integrated charge pump simplifies board layout by reducing external passive components. Consider the thermal performance of the exposed pad package for heat dissipation needs in enclosed automotive housings. Verify input voltage ranges against the vehicle's electrical system specifications.

Part Context
