5. Typical application examples
The following section shows typical application examples. Please refer to additional Melexis application notes
for more details. The signal order in all application diagrams does not reflect any pin order of the device. The
following application diagrams are only principle examples, showing how the controller could be embedded
into a system. Detailed application data must be worked out by customers to meet the needs of their dedicated
application.

MLX81112 is perfectly suited to build highly integrated RGB LED modules.
The PWM output stages allow excellent color and brightness control. The integrated flow current measurement
units can be used to react on aging or other effects of the diodes over life time. For this the initial voltage drop
for a certain forward current is stored in the flash during EOL at customer side, which can be used later to
detect any change in the diode characteristics and adapt the control algorithms accordingly.
