Abstract: A circuit is described that includes a switch, a switchable clamping element coupled to the switch, and a driver configured to control the switch based at least in part on a driver control signal. The driver is further configured to enable or disable the switchable clamping element. The switchable clamping element is configured to clamp a voltage across the switch when the switchable clamping element is enabled by the driver and when the voltage across the switch or a current at the switch satisfies a threshold for activating the switchable clamping element.

Abstract: A gas sensing device comprises a sensing unit for sensing a target gas, the sensing unit comprising a carbon-based sensing layer which is sensitive to the target gas. The gas sensing device further comprises a controller unit for monitoring an exposure of the sensing layer to the target gas. The controller unit further initializes a recovery sequence for the sensing unit depending on an exposure of the sensing unit to the target gas. Further, the gas sensing device comprises a heating electrode for heating the sensing layer during the recovery sequence.

Abstract: A gate driver is described that includes a gate signal module configured to output a gate signal of the gate driver for driving a gate terminal of a semiconductor device. The gate driver further includes a test module configured to generate a simulated failure condition at a semiconductor device during a test of a monitoring and protection feature of the gate driver. The gate drier further includes a monitor module configured to output an indication of the simulated failure condition in response to detecting the simulated failure condition at the semiconductor device.
