Overview
  Green AL8400 /AL8400Q LINEAR LED DRIVER-CONTROLLER with 200mV CURRENT SENSE VOLTAGE and AUTOMOTIVE GRADE Description The AL8400 is a 5-terminal adjustable Linear LED driver-controller offering excellent temperature stability and output handling capability.
The AL8400 simplifies the design of linear and isolated LED drivers.
With its low 200mV current sense FB pin, it controls the regulation of LED current with minimal power dissipation when compared to traditional linear LED drivers.
This makes it ideal for medium to high current LED driving.
Pin Assignments The AL8400 open-collector output can operate from 0.
2V to 18V enabling it to drive external MOSFET and Bipolar transistors.
This enables the MOSFET and Bipolar selection to be optimized for the chosen application.
It also provides the capability to drive longer LED chains, by tapping VCC from the chain, where the chain voltage may exceed 18V.
It is available in the space saving low profile SOT353 package.
The AL8400Q is Automotive Grade and is AEC-Q100 Grade 1 qualified.
Applications • Isolated Offline LED Lamps • Linear LED Driver • LED Signs • Instrumentation Illumination Features • Low Reference Voltage (VFB = 0.
2V) • -40 to +125°C Temperature Range • 3% Reference Voltage Tolerance at +25°C • Low Temperature Drift • 0.
2V to 18V Open-Collector Output • High Power Supply Rejection: ƒ (> 45dB at 300kHz) • AL8400QSE-7 Automotive Grade qualified to AEC-Q100 Grade 1 • SOT353: Available in “Green” Molding Compound (No Br, Sb) ƒ Lead-Free Finish; RoHS Compliant (Notes 1 & 2) ƒ Halogen and Antimony Free.
“Green” Device (Note 3)  Notes: 1.
EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
All applicable RoHS exemptions applied.
