TSCR400CX6H / TSCR402CX6H
Taiwan Semiconductor Linear Constant Current Regulated LED Driver
DESCRIPTION FEATURES 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 ● AEC-Q100 qualified with the following results:
Device temperature grade 1: -40°C to 125°C
Device HBM ESD classification level H2
Device CDM ESD classification level C6
● LED drive current preset:
●
TSCR400CX6: 0.1mA
●
TSCR402CX6: 20mA
● Continuous output current up to 65mA with an
external resistor
● Easy paralleling of drivers to increase current
● Supply voltage up to 40V
● Good temperature coefficient vs. output current
● Compliant to RoHS Directive 2011/65/EU and in
accordance to WEEE 2002/96/EC.
● Halogen-Free according to IEC 61249-2-21 LEDs in strings and will reduce current at increasing
