Abstract
A bus driver circuit may include a first and a second circuit node, wherein the first circuit node is operably coupled to a bus line, which causes a bus capacitance between the first and the second circuit node. A switching circuit is coupled to the first circuit node and configured to apply an output voltage between the first and the second circuit node. Thereby the bus capacitance is charged when a control signal indicates a dominant state. A discharge circuit comprises at least one resistor. The discharge circuit is coupled between the first and the second circuit node and configured to allow the bus capacitance to discharge via the resistor when the control signal indicates a recessive state. The switching circuit is further configured to provide a temporary current path for discharging the bus capacitance during a transition period from a dominant to a recessive state.
