NOT RECOMMENDED FOR NEW DESIGN USE AL5809 AL5890 400V CONSTANT CURRENT LED DRIVER Description The AL5890 is a 400V constant current LED driver and it provides a cost-effective two pin solution. It has good temperature stability and the current accuracy of < ±2.0mA (typ.) regulated over a wide voltage and temperature range. The AL5890 comes in various or pre-fixed output current options removing the need for external current setting resistors and creating a simple driver solution for the series of LEDs. The AL5890 supports both the high-side and low-side driving of LED chains. The AL5890 turns on when the voltage between IN and OUT is greater than 7V. Long LED chain application up to 400V operating voltage subject to package thermal limitation. The AL5890 is available in thermally robust PowerDI®123 (Type B), SOT89 and TO252 (Standard) packages. Pin Assignments (Top View) 1 In 2 Out PowerDI123 (Type B) Features  DC up to 400V Operating Voltage With Long LED Chains Subject to Package Thermal Constraint  LED Current Tolerance Over Wide Temperature Range < ±2.0mA (typ.)  Thermal Foldback Protection  10mA, 15mA, 20mA, 30mA, and 40mA pre-fixed Constant Output Current Options  PowerDI123 (Type B), SOT89 and TO252 (Standard) Thermally Enhanced Packages  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) In 1 Out 2 NC 3 SOT89 In 1 Out 2 2 NC 3 TO252 (Standard) Applications  Commercial LED Lighting Fixtures  Emergency Lighting  Signage, Downlights, Decorative and Architectural Lighting Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.

Stresses greater than the Absolute Maximum Ratings specified above may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time. Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable E.
