Abstract
A Controller Area Network, CAN, device, () is described that includes: a CAN transmitter () connected to two CAN bus terminals () of the CAN device (); a receiver circuit () operably coupled to the two CAN bus terminals () of the CAN device (); and a controller () connected to the CAN transmitter (). The controller () is configured to: determine whether the CAN device () is operating as a transmitter node or a receiver node; detect a transition of the CAN device () from a dominant state to a recessive state; and in response to detecting both a transition of the CAN device () from the dominant state to the recessive state, and the determination of whether the CAN device () is operating as a transmitter node or a receiver node, control an output impedance of the CAN transmitter () to be within an impedance value range whilst a differential driver voltage on a CAN bus () connected to the CAN device () decreases to a predefined voltage.
