... 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 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 ...
