Description
This Linear LED driver is designed to meet the stringent requirements of automotive applications.
The BCR420U monolithically integrates transistors, diodes and resistors to function as a Constant Current Regulator (CCR) for linear LED driving. The device regulates with a preset 10mA nominal that can be adjusted with an external resistor up to 350mA. It is designed for driving LEDs in strings and will reduce current at increasing temperatures to self-protect. Operating as a series linear CCR for LED string current control, it can be used in multiple applications, as long as the maximum supply voltage to the device is < 40V.
With no need for additional external components, this CCR is fully integrated into an SOT26 minimizing PCB area and component count.
