Abstract: Systems, methods, and circuitries are provided to perform bidirectional communication using edge timing in a common signal. In one example, a method includes receiving a common signal on a signal line between a device and another device. The common signal includes a series of signal periods, and each signal period includes a first edge of a first type and a second edge of a second type different from the first type. In each signal period of the series of signal periods: information being communicated by the other device is determined based at least on the determined timing of the first edge and a timing for a subsequent second edge with respect to the signal period is determined based on information to be communicated to the other device. The subsequent second edge is generated at the selected timing in a subsequent signal period of the series of signal periods.

Abstract: A drive circuit includes an internal oscillator and a pre-drive controller coupled to the internal oscillator. The pre-drive controller can have a switch control output configured to be coupled to a switch input. The pre-drive controller can receive switch control data, receive a clock signal, receive a synchronization signal, synchronize the internal oscillator based on the clock signal and the synchronization signal, and generate a pulse modulated switching signal at the switch control output based on the switch control data and the internal oscillator.

Abstract: A circuit includes a first half bridge including a first controllable semiconductor switch and a first diode. The first controllable semiconductor switch is coupled between a first constant supply potential and a center tap of the first half bridge. The first diode is coupled between the center tap and a constant reference potential. A second half bridge includes a second diode and a second controllable semiconductor switch. The second diode is coupled between a second constant potential higher than the first potential and a center tap of the second half bridge. The second controllable semiconductor switch is coupled between the center tap and the constant reference potential. Driver circuitry controls the conducting state of the first and the second semiconductor switch thus controlling the current flow through a field connectable between the center taps.
