BCR402UW6Q
20 TO 100mA LED CONSTANT
CURRENT REGULATOR IN SOT26/SC74R Description Features This Linear LED driver is designed to meet the stringent requirements
of automotive applications. п‚ The BCR402UW6Q monolithically integrates a transistor, diodes and
resistors to function as a Constant Current Regulator (CCR) for LED
driving. The device regulates with a preset 20mA nominal that can be
adjusted with an external resistor up to 100mA. 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 applications with supply
voltages up to 40V.
With no need for additional external components, this CCR is fully
integrated into a SOT26/SC74R minimizing PCB area and component
count. п‚ п‚ п‚ п‚ п‚ LED Constant Current Regulator Using PNP Emitter-Follower with
