Functional Description

The TLE 4242 G is an integrated adjustable constant current source driving loads up to

500 mA. The output current level can be adjusted via an external resistor. The IC is

designed to supply high power LEDs (e.g. Osram Dragon LA W57B) under the severe

conditions of automotive applications resulting in constant brightness and extended LED

lifetime. It is provided in the surface mounted PG-TO263-7-1 package. Protection circuits

prevent damage to the device in case of overload, short circuit, reverse polarity and

overheat. The connected LEDs are protected against reverse polarity as well as excess

voltages up to 45 V.

The integrated PWM input of the TLE 4242 G permits LED brightness regulation by

pulse width modulation. Due to the high input impedance of the PWM input the LED

driver can be operated as a protected high side switch.
