Overview
The NUD4011DR2 is a discontinued low-current LED driver IC from onsemi, designed to replace discrete solutions in AC/DC high-voltage applications up to 200V. It integrates multiple components into an 8-SOIC surface-mount package to reduce system cost and board space. The device provides constant current output with adjustable drive levels via an external resistor, supporting up to 70mA. It features linear PWM dimming capability and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates multiple components into a single SO-8 package to minimize circuit complexity and PCB area.
- Provides stable constant current output for consistent LED brightness across varying input voltages.
- Supports linear PWM dimming for precise light control applications.
Applications
- Portable battery backup lighting systems
- Automotive interior and exterior lighting such as tail lights and turn signals
- General industrial small appliance illumination
Procurement Notes
Verify component authenticity through authorized channels due to the part's end-of-life status. Confirm RoHS compliance requirements as the original DR2 variant may not meet current environmental standards compared to the G suffix version. Ensure design-in compatibility with existing footprints before sourcing obsolete inventory.
Selection Notes
Select this component only for legacy designs requiring specific 200V high-voltage handling capabilities. Evaluate the NUD4011DR2G as a direct replacement if RoHS compliance is mandatory. Consider thermal management constraints inherent to the SO-8 package when designing for continuous operation at maximum current ratings.
Part Context
This device belongs to the NUD4011 series of LED drivers manufactured by onsemi. It serves as a specialized solution for high-voltage LED driving where integration and cost reduction are critical. The series targets applications demanding reliable performance in compact form factors without sacrificing voltage tolerance.
Replacement Considerations
NUD4011DR2G is listed as a direct substitute. Verify pinout and electrical parameter equivalence before implementation. Check for updated environmental certifications required by target markets.
