Abstract: In described examples, an integrated circuit includes first and second current sources, first and second switches, a dV/dt phase detector, a control circuit, and source, gate, and drain terminals for coupling to, respectively, a source, gate, and drain of a power FET. The first switch is coupled between the first current source and the gate terminal. The second switch is coupled between the second current source and the gate terminal. The dV/dt phase detector detects a dV/dt phase of the power FET and outputs to the control circuit. The control circuit controls the first and second switches to perform a turn-on sequence of the power FET, including: closing the first switch while keeping the second switch open; and after receiving a signal from the dV/dt phase detector indicating the dV/dt phase has started, opening the first switch, and closing the second switch.

Abstract: A circuit includes a half-bridge circuit is configured to provide a switching voltage responsive to respective high-side and low-side drive signals. High-side slew control circuitry is configured to provide a high-side slew-compensated control signal responsive to a high-side enable signal and a slew current signal representative of a slew rate at a switching output. A high-side driver is configured to provide the high-side drive signal responsive to the high-side slew-compensated control signal. Low-side slew control circuitry is configured to provide a low-side slew-compensated drive signal responsive to a low-side enable signal and the slew current signal. A low-side driver is configured to provide the low-side drive signal responsive to the low-side slew-compensated control signal. A capacitor is coupled between the high-side and low-side slew control circuitry and is configured to convert the slew rate to the slew current signal.

Abstract: A method for determining neighborhood relationships between an actuator and sensors that interact with the an actuator in an installation for controlling a technical process and that communicate with the actuator, wherein the actuator influences the process and the sensors capture measured values of process variables, where the actuator influences the process in accordance with a predefined test pattern, searches for the predefined test pattern in sequences of measured values received from the sensors as responses to the test pattern, and identifies the sensor whose response best satisfies a predefined quality criterion in terms of response quality and response time as the sensor with the greatest operative proximity to the actuator.

Abstract: An automation system, a controller, a field device and method for operating the automation system, wherein a first field device is provided for an operation on site with an operating unit, where depending on an operator input, the first field device transmits a request for a provision of data to the controller, which returns to the field device corresponding data relating to functionalities in the automation system lying outside the first field device, and where information corresponding to the data is output on the operating unit of the first field device such that an on-site display in the automation system of existing measurement values that were previously not available on the first field device, or a configuration of automation functions which do not run on the first field device is advantageously permitted.
