摘要： A network slave device includes a transceiver for communicating over a communication bus in accordance with a point-to-point network protocol. The network slave device may have an address to identify the network slave device on the network. It may also have a communication circuit configured to process a series of commands received by the transceiver and respond to a command if a position of the command in the series of commands corresponds to the address of the network slave device. A master device communicating on the network may send the series of command in accordance with the point-to-point network protocol. In an embodiment, the point-to-point protocol is the SENT protocol.

摘要： A sensor with multiple magnetic field sensing elements for use in current sensing and other applications is presented. In one configuration, the sensor obtains differential and absolute current measurements of current in current-carrying conductors. When employed in a ground fault interrupter application, a first magnetic field sensing element is used to measure the absolute current flowing in the phase conductor (phase current), a second magnetic field sensing element is used to measure the absolute current flowing in the neutral conductor (neutral current) and a difference between the phase and neutral currents is measured by a third magnetic field sensing element or determined from measurements of the first and second magnetic field sensing elements. In another configuration, a measure of the difference between currents and/or the sum of currents in current-carrying conductors can be obtained. An arrangement of multiple sensing elements may be used for misalignment detection/correction.
