TSCR400CX6H RFG Taiwan Semiconductor

TSCR400CX6H / TSCR402CX6H Taiwan Semiconductor Linear Constant Current Regulated LED Driver DESCRIPTION FEATURES AEC-Q100 qualified with the following results: The TSCR400 & TSCR402 are High-Side Constant - Device temperature grade 1: -40C to 125C Current Regulator (CCR) for linear LED driving. The - Device HBM ESD classification level H2 device regulates with a preset TSCR400 0.1mA and - Device CDM ESD classification level C6 TSCR402 20mA nominal that can be adjusted with an LED drive current preset: external resistor up to 65mA. It is designed for driving TSCR400CX6: 0.1mA LEDs in strings and will reduce current at increasing TSCR402CX6: 20mA temperatures to self-protect. Operating as a series Continuous output current up to 65mA with an linear CCR for LED string current control, it can be external resistor used in multiple applications, as long as the maximum Easy paralleling of drivers to increase current supply voltage to the device is <40V. Supply voltage up to 40V The output current at higher temperatures is the result Good temperature coefficient vs. output current of the negative temperature coefficient of -0.07%/C of Compliant to RoHS Directive 2011/65/EU and in the LED driver. accordance to WEEE 2002/96/EC.
