E522.90/91/92/93
Features
General Description
Three independent high-side Current Sources (3*55mA)
E522.90/91/92/93 family features independent triple linear
high-side current sources for LED driving. Diagnostic features
are provided to meet automotive requirements, together
with a communication interface “RUN” to link ICs fault han-
dling. Individual current configuration and independent dig-
ital PWM dimming per channel are available (e.g. for RGB).
Full functional compatibility with higher current versions
E522.80-83 allows drop-in replacement and thus simplest
adaption of existing solutions in current range.
Redundant Outputs for each Channel
Parallel Operation for up to 165mA
Low Power Standby / Sleep Mode
Thermal Management Option per Channel
Operating Input Voltage Range 5V to 25V, max. 40V
External Reference Voltage / Derating Supported
PWM Dimming (All channels or separate Channels)
Diagnostic Functionalities (LED Driver Open/Short, IR Config
Open/Short, Junction Temperature, Supply Voltage)
Diagnostic Bus to link ICs
Two external configurable modes of operation allow
- either “Failure Feedback Mode” FFM (operating channels in
case of errors, with error signalization)
Selectable “Failure Feedback Mode” or “Single Lamp Behaviour”
Drop-In Functional compatibility to E522.80
AEC-Q100 Qualification
- or in “Single Lamp Mode” (turning all linked E522.9x´s chan-
nels “off” in case of errors)
Applications
Automotive LED Lighting, Rear Lighting
An intelligent power management system is provided using
an external shunt resistor to share power distribution be-
tween E522.9x and external heat sink. Hotspot generation
can be avoided by flexible heat spreading. Internal derating
for reference voltage and over-temperature shut-down for
extreme temperatures >180°C protect E522.9x in case of ab-
normal operation conditions.

Medium Current Interior Lighting
Industrial LED Applications or RGB Drivers
Ordering Information
A high voltage capable input ENA can be used to either dig-
itally enable or disable E522.9x. Furthermore, ENA may be
used as analog reference voltage input.
