[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
