Abstract: A circuit (e.g., implemented as part of a controller area network (CAN) bus receiver includes a pre-amplifier stage having first and second outputs. The circuit also includes a comparator having first and second inputs. The first input is coupled to the first output of the pre-amplifier stage, and the second input is coupled to the second output of the pre-amplifier stage. The comparator includes an input differential transistor pair, a second pair of transistors coupled to the input differential transistor pair in a cascode configuration, and a push-pull output stage coupled to the second pair of transistors.

Abstract: A system basis chip (SBC) includes a serial peripheral interface for communication with a processor, a set of registers for storing information operable to control an external communication interface device, and a control signal output adapted to be coupled to the external communication interface device. In some implementations, the set of registers includes a first register for information indicative of a function of the control signal, and a second register for information indicative of a value of the control signal. The function of the control signal for the external communication interface device can be a supply voltage interrupt, a watchdog interrupt event, a counter-based watchdog interrupt event, a local wakeup request, a bus wakeup request, an entrance into a fail-safe mode of operation, or a general purpose output signal. In some implementations, the SBC also includes a supply voltage output adapted to be coupled to the external communication interface device.

Abstract: A transceiver includes a driver stage and a transient-triggered ring suppression circuit. The driver stage has a first transistor coupled between a supply voltage terminal and a first bus terminal and a second transistor coupled between a ground and a second bus terminal. The transient-triggered ring suppression circuit is coupled to the first and second transistors. The transient-triggered ring suppression circuit is configured to be enabled upon transition of the transceiver from a dominant state to a recessive state. Further, while the transceiver is in the recessive state, the transient-triggered ring suppression circuit is configured to attenuate ringing on at least one of the first or second bus terminals.
