NUD4001, NSVD4001
High Current LED Driver
This device is designed to replace discrete solutions for driving
LEDs in low voltage AC −DC applications 5.0 V, 12 V or 24 V. An
external resistor allows the circuit designer to set the drive current for
different LED arrays. This discrete integration technology eliminates
individual components by combining them into a single package,
which results in a significant reduction of both system cost and board
space. The device is a small surface mount package (SO–8).
Features
• Supplies Constant LED Current for Varying Input Voltages
• External Resistor Allows Designer to Set Current – up to 500 mA
• Offered in Surface Mount Package Technology (SO−8)
• AEC−Q101 Qualified and PPAP Capable
• NSV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements
• Pb−Free Package is Available
Benefits
• Maintains a Constant Light Output During Battery Drain
• One Device can be used for Many Different LED Products
• Reduces Board Space and Component Count
• Simplifies Circuit and System Designs
Typical Applications
• Portables: For Battery Back−up Applications, also Simple Ni−CAD
Battery Charging
• Industrial: Low Voltage Lighting Applications and Small Appliances
• Automotive: Tail Lights, Directional Lights, Back−up Light,
Dome Light
