MLX81112/15
Single and Dual Channel LIN RGB Controller
Short Datasheet
[1] ISO 7637 test pulses are applied to VS via a reverse polarity diode and >1µF blocking capacitor;
[2] ISO 7637 test pulses are applied to LIN via a coupling capacitance of 1nF;
[3] Simulated value for low conductance board (JEDEC).
[4] Equivalent to discharging a 150pF capacitor through a 330Ω resistor;
[5] Based on the evaluation results, additional external protection components might be recommended to reach the
specified system ESD levels.
[6] Equivalent to discharging a 100pF capacitor through a 1.5kΩ resistor conform to MIL STD 883 method 3015.7.
4. Operating conditions
 The IC can have 6 different hardware modes. The exact functionality of these modes depends on the
hardware and software configuration:
 Reset:
o Triggered by hardware. When VS or VDDA or VDDD drop below a critical level, the complete
chip is powered down.
o The analogue and digital supply regulators are disabled. No functionality is available in this
mode.
 Normal mode. Main application running
o Microcontroller fully functional
o Analogue fully functional
 Low power mode (managed via firmware). Digital part running at lower frequency (250kHz)
o Microcontroller fully functional
o LIN not possible
o Analogue fully functional
 Under voltage: triggered by the hardware under voltage detection interrupt
o Microcontroller fully functional.
o Power down behavior can be managed via software.
o Reduced current capability on HVx below VS=5.5V.
 Over voltage: triggered by the hardware over voltage detection interrupt.
o Microcontroller fully functional
o Behaviour can be managed via software.
 Sleep Mode: Triggered by the software.
o Microcontroller powered down
o Digital and analogue supply powered down.
o Sleep Mode and wake-up functionality running on help supply Vaux
