1. VSREG not floating

2. Related to the external supply pin of the CAN-transceiver. If the transceiver supply is generated entirely inside of the device

the parameter is measured with respect to the supply of the device.

3. Related to the external supply pin of the CAN-transceiver. If the transceiver supply is generated entirely inside of the device

the parameter is measured with respect to the supply of the device; if the transceiver is supplied by its own supply pin, this

pin has to fulfill this specification as well as the supply that is used to generate the transceiver voltage in case it is on the

same device.

4. Related to the external supply pin of the CAN-transceiver. If the transceiver supply is generated entirely inside of the device

LIN transceiver (only for SPSB0815 & SPSB0813)

LIN ISO 17987-6:2016 compliant

For data rates up to 20 Kbit/s

The voltages are referred to GND and currents are assumed positive, when the current flows into the pin.

6 V < VSREG< 18 V; Tjunction = from -40°C to 150°C unless otherwise specified.
