Triple 150mA Linear LED Controller E522.80/81/82/83 Production Data - May 5, 2017 Features General Description Three independent Linear Current Drivers (3*150mA) E522.80/81/82/83 family devices provide independent triple Parallel Output Operation for up to 450mA linear current controller for LED driving (standalone driver or Low Power Standby / Sleep Mode LED cluster). Diagnostic features are provided to meet auto- Thermal Management Option per Channel motive requirements, together with a communication inter- Operating Input Voltage Range 5V to 25V, max. 40V face “RUN” to link ICs to generate more than three channels, External Reference Voltage / Derating Supported supporting individual current configuration and independent PWM Dimming (All channels or separate Channels) digital PWM dimming per channel (e.g. for RGB). Diagnostic Functionalities (LED Driver Open/Short, IR Config Open/Short, Junction Temperature,Supply Voltage) Two external configurable modes of operation allow Diagnostic Bus to link ICs - either “Failure Feedback Mode” FFM (operating channels in Selectable “Failure Feedback Mode” or case of errors, with error signalization) “Single Lamp Behaviour” - or in “Single Lamp Mode” (turning all linked E522.8x´s chan- AEC-Q100 Qualification nels “off” in case of errors) Applications An intelligent power management system is provided using Automotive LED Lighting, Rear Lighting an external shunt resistor to share power distribution be- Turn Indicator Driver tween IC package and external heat sink.
