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 handling. Individual current configuration and independent digital 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.
Two external configurable modes of operation allow
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.
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.
