    Abstract: Examples disclosed herein involve integrated circuit chip arrangements. An example integrated circuit (IC) package may include a first semiconductor chip that includes a first metal-oxide-semiconductor field-effect transistor (MOSFET) and a second semiconductor chip mounted within a housing of the IC package. The second semiconductor chip may include a second MOSFET and a control circuit configured with a first driver for the first MOSFET and a second driver for the second MOSFET. The first semiconductor chip may be mounted to the second semiconductor chip opposite a base of the IC package.

    Abstract: An embodiment electronic circuit includes an electronic switch comprising a load path, a first protection circuit configured to generate a first protection signal based on a current-time-characteristic of a load current through the load path of the electronic switch, and a drive circuit configured to drive the electronic switch based on the first protection signal. The first protection circuit includes an analog-to-digital converter (ADC) configured to receive an ADC input signal representing the load current, to sample the ADC input signal once in each of a plurality of successive sampling periods, and to output an ADC output signal that includes a sequence of values such that each of the values represents a respective sample of the ADC input signal. The ADC is configured to pseudo-randomly select a sample time in each sampling period.

    Abstract: A power circuit is described that includes a switch coupled to a resistive-inductive-capacitive load and a driver coupled to the switch. The driver is configured to detect an emergency event within the power circuit. After detecting the emergency event within the power circuit, the driver is further configured to perform a controlled emergency switch-off operation of the switch to minimize the maximum temperature of the switch during the detected emergency event and switch-off operation.

    Abstract: An embodiment electronic circuit includes an electronic switch comprising a load path, and a control circuit configured to drive the electronic switch. The control circuit is configured to operate in one of a first operation mode and a second operation mode based at least on a level of a load current of the electronic switch. In the first operation mode the control circuit is configured to generate a first protection signal based on a current-time-characteristic of the load current and drive the electronic switch based on the first protection signal. The control circuit is configured to generate a status signal such that the status signal has a wakeup pulse when the operation mode changes from the second operation mode to the first operation mode and, after the wakeup pulse, a signal level representing a level of the load current.
