TLD1211SJ

The TLD1211SJ is an integrated adjustable constant current source realized in a bipolar IC technology

TLD1211SJ IC drives high-current, high-brightness LEDs in cars, ensuring constant brightness and extended lifespan. It supports up to 2.5A with external stages and 85mA standalone use. Protection circuits prevent damage from overload, short circuit, overvoltage, and overtemperature. Temperature-dependent current reduction protects thermally coupled LEDs. The integrated EN input enables LED brightness control via pulse width modulation.
