Product data sheet
7.4 Configuration pins C1 to C3
7.5 LIN transceiver
The structure of the configuration pins C1 to C3 (Cx) is shown in
a pull-up to the battery. The pull-up is switched on during node address configuration only.
In all other cases the Cx have high-impedance behavior.
In order to have a safety margin against ground shift the input threshold of the
configuration pins is about 0.5 × V
In addition the configuration pin C3 has a low-side driver to provide the output signal
during daisy chain ID configuration.
The integrated LIN transceiver of the UJA1023 is compliant with LIN 2.0 / SAE J2602 and
provides:
