A device for a single wire digital bus, includes an interface for the bus configured to receive a request to arbitrate for an address and to transmit device specific data on the bus upon receipt of the request to arbitrate for an address The device further includes a control circuit configured to determine, if a further device transmits device specific data on the bus, and to use the address arbitrated for, if no further device transmits device specific data on the bus.

Device for a single wire digital bus, master device, sensor, and method to assign addresses to multiple devices on a single wire digital bus

Embodiments relate to systems and methods for self-diagnostics and/or error detection using multiple signal paths in sensor and other systems. In an embodiment, a sensor system comprises at least two sensors, such as magnetic field sensors, and separate signal paths associated with each of the sensors. A first signal path can be coupled to a first sensor and a first digital signal processor (DSP), and a second signal path can be coupled to a second sensor and a second DSP. A signal from the first DSP can be compared with a signal from the second DSP, either on-chip or off, to detect faults, errors, or other information related to the operation of the sensor system. Embodiments of these systems and/or methods can be configured to meet or exceed relevant safety or other industry standards, such as safety integrity level (SIL) standards.

Sensor self-diagnostics using multiple signal paths

Methods, systems and devices related to bidirectional edge-based pulse width modulation communication systems are disclosed. In some implementations, upon receipt of a predetermined trigger pulse at least two slave devices perform an action.
