AL8400 /A L8400Q LINEAR LED DRIVER-CONTROLLER with 200mV CURRENT

SENSE VOLTAGE and AUTOMOTIVE GRADE

性能描述：
      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.
     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.
