Additional Infomation About Product

TSCR420 TSCR421 TSCR420CX6H / TSCR421CX6H Taiwan Semiconductor Linear Constant Current Regulated LED Driver DESCRIPTION FEATURES The TSCR420 & TSCR421 are Low-Side Constant AEC-Q100 qualified with the following results: - 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 10mA nominal that can - Device CDM ESD classification level C6 be adjusted with an external resistor up to 300mA. It is LED drive current preset to 10mA designed for driving LEDs in strings and will reduce Continuous output current up to 300mA with an current at increasing temperatures to self-protect. external resistor Operating as a series linear CCR for LED string Very low enable current current control, it can be used in multiple applications, Easy paralleling of drivers to increase current as long as the maximum supply voltage to the device Supply voltage up to 40V is <40V. Digital PWM input up to 10kHz (TSCR421) With the low-side control, the TSCR421 has an Enable Good temperature coefficient vs. output current (EN) pin which can be pulse-width modulated (PWM) Compliant to RoHS Directive 2011/65/EU and in up to 10kHz by a microcontroller for LED dimming. accordance to WEEE 2002/96/EC. The output current at higher temperatures is the result Halogen-Free according to IEC 61249-2-21 of the negative temperature coefficient of 0.07%/C of APPLICATION the LED driver.
