The TSCR400 & TSCR402 are High-Side Constant Current Regulator (CCR) for linear LED driving. The device regulates with a preset TSCR400 0.1mA and TSCR402 20mA nominal that can be adjusted with an external resistor up to 65mA. 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> The output current at higher temperatures is the result of the negative temperature coefficient of -0.07%/°C of the LED driver.
