Infineon® Basic LED Driver
Flexible linear current source family with scalable feature set
Infineon’s Basic LED driver are optimized for the control
of low to medium power LEDs in automotive applications.
The whole family of linear constant current sources oers
footprint compatibility ranging from 1 to 3 output channels
and 60–180mA and enables stable and reliable LED
brightness by precise current control.
Its diagnostics and logic feature set enables improved
system reliability by significant component reduction on
board level, improved system protection (e.g. against ISO
pulses), as well as an energy optimized system solution
(DC/DC control).
PWMI = Internal PWM dimming engine
N - 1 = Complete device deactivation during Open Load
OL = Open Load Diagnosis
SC = Short Circuit Diagnosis
DEN = Diagnosis Enable Input
Matrix = Feedback to DC/DC to optimize efficiency
