K52283-0001

E522.83 provide independent triple linear current controller for LED driving (standalone driver or LED cluster). Diagnostic features are provided to meet automotive requirements, together with a communication interface “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).An intelligent power management system is provided using an external shunt resistor to share power distribution between IC package and external heat sink. Hotspot generation can be avoided by flexible heat spreading on the printed board. Internal derating for reference voltage and over-temperature 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 either digitally enable or disable E522.8x. In addition, this input may be used as analog reference voltage input to realize e.g. thermal derating.

• Three independent Linear Current Drivers (3*150mA)
• Operating input voltage range 5V to 25V, max. 40V
• Advanced diagnostic features Open / short detection Diagnostic “RUN” bus to link multiple ICs
• Different start-up voltages for open diagnostics can be chosen: VS=7.5V, 9V, 10V and 15V
• Single Lamp” mode disables all LEDs in case of a failure
