The IC is designed to supply LEDs under the severe conditions of automotive applications resulting in constant brightness and extended LED lifetime. The TLD1211SJ is capable to drive high current, high brightness LEDs up to 2.5 A by using additional external output stages as “booster“ transistors. For LED currents up to 85mA the IC can be used as a stand alone device and requires only one voltage sense resistor as an external component. Protection circuits prevent damage to the device in case of overload, short circuit, over voltage, and overtemperature. Furthermore, the temperature dependent current reduction is able to protect LEDs which are thermally coupled to the IC. The integrated EN input of the TLD1211SJ enables LED brightness control by pulse width modulation.

The TLE4241GM provides an output current adjustable via different means (SET, PWM, reference resistor) which is kept nearly independent from load and supply voltagechanges. The IC is designed to supply LEDs under the severe conditions of automotive applications resulting in constant brightness and extended LED lifetime. It is provided in the very small PG-DSO-8-16 (Micro 8) package. Protection circuits prevent damage to the device in case of overload, short circuit, reverse polarity and overtemperature. The connected LEDs are protected against reverse polarity as well as excess voltages up to 45 V. 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.
