Introduction

AI Translation

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. The AL8400 Linear LED driver controller uses an external pass element to drive the LEDs and uses its FB pin to sense the LED current through an external resistor RSET. The pass element is driven by the AL8400’s open collector OUT pin which allows the pass element to be either an NPN transistor or N-channel MOSFET. An external pull-up resistor, RB, is required to be connected from the OUT pin to VCC. This resistor supplies the output bias current of the AL8400 together with any current which the pass element requires. In order to maintain the accuracy of the 200mV reference voltage on the FB pin the value of RB should be set so that the OUT pin sinks 1mA.
