JAJSH69B January 2018 – November 2019 TCAN4550-Q1
Bus biasing can be normal biasing, active in normal mode and inactive in low-power mode. Automatic voltage biasing is where the bus is active in normal mode but is controlled by the voltage between CANH and CANL in lower power modes. See Figure Figure 104 for the state diagram on how the TCAN4550-Q1 performs automatic biasing. Figure Figure 105 provides the bus biasing based upon the mode of operation.
