The TLE4242G is an adjustable constant‑current LED driver designed for automotive‑grade high‑power LEDs. It provides up to 500 mA of current, a wide input voltage range, and integrated protection against overload, short circuit, reverse polarity and over‑temperature. The device includes a PWM input for brightness control and can operate as a high‑side switch.
The datasheet details the functional description, pin configuration, typical application circuit, absolute maximum ratings, operating ranges, electrical characteristics and package dimensions. It also includes timing diagrams for the status and PWM functions and legal disclaimer information.
| Maximum adjustable current | 500 mA |
|---|---|
| Operating temperature range | -40 °C – 150 °C |
| Drop voltage at 300 mA | 0.7 V max |
Brightness is controlled via the PWM input pin, which modulates the LED current by duty cycle.
