Infineon TLE 4242 G LED Driver Datasheet
The TLE 4242 G is an integrated adjustable constant‑current LED driver designed for automotive‑grade applications. It supplies up to 500 mA to high‑power LEDs and includes protection against overload, short‑circuit, reverse polarity, and over‑temperature.
Key features include a wide input voltage range (4.5 V to 42 V), PWM‑controlled brightness, open‑load detection, and a low drop voltage. Typical application circuits use an external shunt resistor to set the desired current, while the status output pin indicates load conditions. The device is offered in a surface‑mounted P‑TO263‑7‑1 package.
