driven with an adequate supply current adjusted by the resistor
variations due to forward voltage spread of the LEDs are prevented. The luminosity
spread arising from the LED production process can be compensated via software by an
appropriate duty cycle applied to the PWM pin. Hence selection of the LEDs to forward
voltage as well as to luminosity classes can be spared. The slightly negative temperature
coefficient of the TLE 4241 GM output current protects the LEDs against over-
temperature stress if the IC is placed nearby the LEDs.
The voltage drop (
open load condition indicated at the status output pin ST. In case of open load, the
voltage drop will decrease below the lower status switching threshold
status output ST will be driven low. In normal operation, the voltage drop is above the
upper status threshold
