Operating Modes

The TCAN104xAV-Q1 has two main operating modes; normal mode and standby mode. Operating mode selection is made by applying a high or low level to the STB or nSTB pins on the TCAN1046A or TCAN1048A device respectively.

Table 10-3 Operating Modes
STB nSTB Device Mode Driver Receiver RXD Pin
High Low Standby mode Disabled Low-power receiver with bus monitor enable High (recessive) until valid WUP is received
See section Section 10.4.3.1
Low High Normal Mode Enabled Enabled Mirrors bus state
