General Description
E522.80/81/82/83 family devices provide independent triple
linear current controller for LED driving (standalone driver or
LED cluster). Diagnostic features are provided to meet auto-
motive requirements, together with a communication inter-
face “RUN” to link ICs to generate more than three channels,
supporting individual current configuration and independent
digital PWM dimming per channel (e.g. for RGB).
Two external configurable modes of operation allow
- either “Failure Feedback Mode” FFM (operating channels in
case of errors, with error signalization)
- or in “Single Lamp Mode” (turning all linked E522.8x´s chan-
nels “off” in case of errors)
An intelligent power management system is provided using
an external shunt resistor to share power distribution be-
tween IC package and external heat sink. Hotspot genera-
tion can be avoided by flexible heat spreading on the printed
board. Internal derating for reference voltage and over-tem-
perature shutdown for extreme temperatures >180°C pro-
tect E522.8x in case of abnormal operation conditions.

A high voltage capable input ENA can be used to either digi-
tally enable or disable E522.8x. In addition, this input may be
used as analog reference voltage input to realize e.g. thermal
derating.
