摘要： An apparatus for controlling a high-power drive device external to a package of a motor drive circuit includes a motor drive circuit. The motor drive circuit includes a driver to control the high-power drive device based on a first reference voltage, a second reference voltage, and a control signal based on a received control signal. A fault circuit generates a failure indicator based on a voltage across terminals of the high-power drive device. A fault condition is based on the failure indicator. A first terminal coupled to the driver charges a node of the high-power drive device over a first length of time in response to an absence of the fault condition and a first level of the control signal. A second terminal coupled to the driver discharges the node over a second length of time different from the first length of time.

摘要： An apparatus for communicating using an isolation channel includes a transmitter circuit having a first terminal configured to communicate a first signal. The first signal oscillates in response to a data signal having a first signal level and is constant in response to the data signal having a second signal level. The transmitter circuit includes a second terminal configured to communicate that oscillates in response to the data signal having the second signal level and is constant in response to the data signal having the first signal level. The apparatus may include a receiver circuit configured to generate a recovered data signal having a first transition in a first direction between first and second levels based on an edge of a first received signal and having a second transition in a second direction between the first and second levels based on an edge of a second received signal.

摘要： Current flowing through an inductor on a primary side of a voltage converter is sensed and compared to a threshold peak current value to determine when to end an ON portion of the voltage converter. The secondary side of the voltage converter supplies an indication of output voltage for use in determining the threshold peak current value. On start-up the primary side detects when the indication of output voltage is supplied by the secondary side across on isolation channel. Prior to detecting the indicating is being supplied, the primary side uses an increasing threshold peak current as the threshold peak current value. After detection that the indication of output voltage is being provided by the secondary side, the threshold peak current value is based on the indication of the output voltage.

摘要： An apparatus includes a first terminal, a second terminal, a bi-directional regulator circuit, and functional circuitry. The bi-directional regulator circuit generates a voltage across a first power supply node and a second power supply node in response to an input current flowing through the first terminal and the second terminal with a first polarity. The bi-directional regulator circuit also generates the voltage across the first power supply node and the second power supply node in response to the input current flowing through the first terminal and the second terminal with a second polarity opposite the first polarity. The functional circuitry is powered by the voltage and is configured to generate a signal using the voltage. The signal is indicative of the input current in response to the input current being supplied to the first terminal and is indicative of the input current in response to presence of the input current.

摘要： A first integrated circuit die receives input data from a plurality of input channels and combines the input data from the plurality of input channels into combined data. The first integrated circuit die transmits the combined data across an isolation communication channel. A second integrated circuit die that is coupled to the isolation communication channel decodes the transmitted combined data and supplies the decoded transmitted combined data to respective output channels corresponding to the input channels.
