General Description
E522.84/85/86/87 family devices provide triple linear current
controller for LED driving (standalone driver or LED cluster).
Diagnostic features are provided to meet automotive re-
quirements, together with a communication interface “RUN”
to link ICs to generate more than three channels, supporting
common current configuration per IC and including digital
PWM dimming via fast ENA.
“Single Lamp Mode” allows to simulate the fail-behaviour of
a single bulb to e.g. meet legal restrictions regarding lighting.
Internal derating for reference voltage and overtemperature
shutdown for extreme temperatures >180°C protect E522.8x
in case of abnormal operation conditions.
A high voltage capable input ENA can be used to digitally en-
able or disable E522.8x. In addition, this input may be used
as analog reference voltage input, e.g. to realize thermal de-
rating.
