The inrush-current is below 30 A.
Condition: V_Batt=14.0V, 5m wire harness length, 0.5mm²
Typical inrush current plot for 5mtr wiring harness:
3.2.3.
Mounting recognition
The mounting recognition is used to determine the location of the SCU inside the vehicle through
configuration of the wire harness. This can be read out and used by the software to configure the
sensor. Depending on the SCU configuration, one or more Mounting Recognition circuits are
available.
External termination of the vehicle connector pin for separation of two mounting positions (e.g.
right/left or front/rear):
- termination to GND
- no termination OPEN
A short circuit of the Vehicle Connector Pin against supply voltage can be recognised by the SW
as error.
It is not possible to detect the errors short circuit to GND or open connection at the vehicle
connector pins since they are used as valid input states (see above).
The circuit is not robust against a short circuit to V_BATT at the used vehicle connector pin(s)
and application of reverse polarity at the same time.
