Abstract: Systems and methods related to serial communication devices are provided. An example integrated circuit (IC) device includes interface circuitry coupled to a two-wire serial communication bus having a serial clock (SCL) line and a serial data (SDA) bus line. The IC device further includes bus stuck recovery circuitry to monitor for a local SDA fault condition at the IC device based on a number of clock cycles during which an internal SDA signal (e.g., generated by the IC device) drives the SDA bus line to a first signal state, the clock cycles based on a clock signal received from the SCL line; and responsive to the local SDA fault condition, release the SDA bus line independent of the internal SDA signal, where the SDA bus line is in a second signal state different from the first signal state based on the release.

Abstract: An apparatus includes a nozzle including a small die vacuum line disposed on a surface of the nozzle, and a large die vacuum line disposed on the surface and surrounding the small die vacuum line. The nozzle further includes a first die vacuum hole disposed through the surface and the small die vacuum line, and a second die vacuum hole disposed through the surface and the large die vacuum line. The small die vacuum line and the first die vacuum hole are configured to provide a vacuum to a small semiconductor die to be attached to a substrate, and the small die vacuum line, the large die vacuum line, the first die vacuum hole and the second die vacuum hole are configured to provide the vacuum to a large semiconductor die to be attached to the substrate.

Abstract: A high frequency converter for driving a gas discharge lamp load is comprised of an input stage for receiving an AC input voltage and rectifying the input voltage to create a DC voltage source, an oscillating power inverter, an output stage connected to the power inverter, and a trigger circuit used to initiate oscillations in the power inverter. The trigger circuit further comprises a voltage ramp circuit. The output stage includes a transformer having a center tap and two capacitors of equal value connected from the tap to each end of the transformer. The capacitors and transformer form two resonant tanks. Also, an RF choke may be connected between the center tap and the source of DC voltage.

Abstract: A line current filter for less than 10% total harmonic distortion includes an isolation transformer having two mutually coupled coils connected to an AC power source and a voltage rectifier. A shunt circuit is connected in parallel to one of the mutually coupled coils. The shunt circuit is comprised of a series connected resistor and capacitor. The shunt circuit may also include a second resistor connected in parallel to the capacitor. A second capacitor is connected across the two mutually coupled coils between the isolation transformer and the DC rectifier.
