Infineon® Auto LED Driver are an enabler of protected and
high performing lighting applications in automotive.
In particular the constant current regulation secures the
stable brightness of the LED over the whole automotive
temperature and voltage range.
Applications
The Infineon automotive optimized LED Drivers address
interior and exterior, low to high power automotive
LED applications such as: high and low beam, fog, DRL,
position, tail, stop, CHMSL, RCL, reverse, turn indicator,
dome, ambient lighting, status lamps etc.

The driver as well as the LED are protected gainst overstress
e.g. caused by voltage spikes or overtemperature.
Any kind of load conditions are detected by its diagnostic
features such as open load or shorted LED.
All features are required to drive LEDs in harsh automotive
environment conditions.
