Always keep cool at 450mA. Unique Thermal Management.

Simplify your System: One IC, manifold applications, always fantastic performance

Elmos presents a powerful product family for LED applications. The LED controller and driver family is available with 450mA or 3 times 150mA per channel (E522.80/81/82/83) and 180mA or 3 times 60mA per channel (E522.84/85/86/87) output current. The E522.46 provides eight linear high side current sources for LED driving.

Keep your Light cool!

Controller: You gain an excellent thermal load balancing between internal and external power dissipation by using external ballast resistors in combination with two in parallel operating linear current sources.
Driver: An internal power management system including a current source shut-off above TJunc=+165°C guarantees an appropriate power dissipation of the system.

Know your Light!

Controller: The outstanding features are extensive diagnostic that ensure a reliable operation of the power stage with open/short detection, monitoring the junction temperature, voltage control and internal or optional external temperature compensation.  
Driver: The luminous intensity level of each LED is adjusted by a common analog master current and an individual PWM duty cycle, considering the stored binning information

Design your Light!

Controller: Shared and specific PWM dimming is possible to build up powerful LED applications.
Driver: Global PWM and configurable analog dimming is possible.

Keep your Lighting Application Simple!

Controller: Another unique feature of the LED controller ICS are the “Run” pin, with this “Run” pin you can generate a “single lamp mode”, independent how many LEDs you have to drive.
Driver: Due to the synchronizable master-slave characteristic and adjustable error handling with a common INTB error bus the E522.46 is also designed to drive cluster applications and a higher number of LED channels.
