DATA SHEET .onsemi. High Current LED Driver NUD4001, NSVD4001 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 ponents by bining 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 m A - Offered in Surface Mount Package Technology (SO- 8) - NSV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC- Q101 Qualified and PPAP Capable - 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 ponent 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 PIN FUNCTION DESCRIPTION Pin Symbol Description Vin Positive input voltage to the device Boost This pin may be used to drive an external transistor as described in the App Note AND8198/D. Rext An external resistor between Rext and Vin pins sets different current levels for different application needs 4 5, 6, 7,...
