The functionality is not robust against a parallel resistance of 5kOhm to V_BATT. This will be
recognized as short circuit to V_BATT error. No damage to the circuit will be caused.
Hint:
To increase error detection capability, it is possible to use two Mounting Recognition circuits (if
available) for distinguishing two states. The external termination at the vehicle connector pins
should be as follows:
Position1:
1st pin terminated to GND
2nd pin left OPEN
Position2:
1st pin left OPEN
2nd pin terminated to GND
Thus, following unwanted states at one or both Vehicle Connector Pins can be recognised by the
SW as errors:
- Short circuit to supply voltage
- Short circuit to GND
- Interrupted connection (Open Load)
This product is an electronic device and sensitive to electrical discharge. Therefore, ESD standard
protection according to IEC 61340-5-1 and IEC 61340-5-2 have to be obeyed at all times during
handling and transportation. E.g. the pins of the product must not be touched at any time.
