TLE4241GM

The TLE4241GM is an integrated Adjustable Constant Current Source provides an output current adjustable via different means (SET, PWM, reference resistor) which is kept nearly independent from load and supply voltage changes. Protection circuits prevent damage to the device in case of overload, short circuit, reverse polarity and over-temperature. The connected LEDs are protected against reverse polarity as well as excess voltages up to 45V. A status output allows handling of open load and short circuit at the main output. A PWM input offers the possibility to adjust the LED brightness by pulse width modulation. With an implemented high/low current switch the output current level can be reduced for brake/tail light application. The implemented features such as adjustable output current, the high/low current switch and the provided PWM input make the device well suited for a broad range of LED and other applications.
