  • Patent number: 11916544
    Abstract: A method for driving a power transistor includes comparing a measurement signal that is representative of a load current to a comparator threshold that corresponds to an overcurrent threshold; generating a first fault signal when the measurement signal exceeds the comparator threshold for a first time interval; generating a second fault signal when the measurement signal exceeds the comparator threshold for a second time interval that is greater than the first time interval; regulating a control voltage provided to the control terminal of the transistor to turn off the transistor in response to the second fault signal; and in response to the first fault signal, adjusting the control voltage to an adjusted voltage level in order to limit the load current to a reduced current level that is preconfigured to be greater than the overcurrent threshold. The adjusted voltage level is sufficient to maintain the power transistor in an on-state.

  • Publication number: 20230275577
    Abstract: A transistor device is provided including a first device load terminal, a second device load terminal and a device control terminal. The device includes a transistor. A first transistor load terminal is coupled to the first device load terminal, a second transistor load terminal is coupled to a second device load terminal, and a transistor control terminal is coupled to the device control terminal via a variable impedance element. An overload detection circuit switches the variable impedance element from a first state with lower impedance to a second state with higher impedance in response to detecting an overload condition.

  • Patent number: 11728737
    Abstract: An apparatus may include an electric power converter and pre-charge circuitry. The electric power converter may include a first circuit, a second circuit and an energy transfer device. The first circuit may be connected to a power supply. The second circuit may be connected to a load. The energy transfer device may have a first side connected to the first circuit and a second side connected to the second circuit. The pre-charge circuitry may be connected to a capacitor of the first circuit. The capacitor may be connected to the first side of the energy transfer device. The pre-charge circuitry may be configured to charge the capacitor during a pre-charge mode of the electric power converter. The electric power converter may be configured to exit the pre-charge mode and enter an energy transfer mode responsive to a charge level of the capacitor reaching a threshold pre-charge level.

  • Publication number: 20160003663
    Abstract: Capacitive liquid level measurement uses differential out-of-phase (OoP) channel drive to counteract human body capacitance. In an example embodiment, a container assembly includes a capacitive sensor with symmetrical CHx and CHy capacitor electrodes, corresponding in height to a liquid level measurement range. A CHx driver provides a CHx excitation/drive to the CHx electrode, and a CHy driver provides OoP CHy excitation/drive to the CHy electrode that is substantially 180 degrees out-of-phase with the CHx drive. Capacitance associated with the liquid level is measured by acquiring capacitance measurements through the CHx channel (such as based on capacitive charge transfer), and converting the capacitance measurements to an analog voltage corresponding to liquid-level capacitance (which can then be converted to digital data). The capacitive sensor can be configured with SHLDx/SHLDy shields disposed behind, and driven in phase with, respective CHx/CHy electrodes.
