Abstract: A system includes multiple devices connected in a chain-like structure, each device of the multiple devices coupled to at least one bus. A device of the plurality of devices includes a circuit configured to detect activity of a differential signal of a bus coupled to the device to cause a wakeup of the device in response to the detection.

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: In one example, a method includes generating, by a main switching element of a device, a load current; generating, by a regulation loop of the device, a sense current proportional to the load current; directly converting, by an analog-to-digital converter (ADC) of the device, the sense current into a digital sense current value; and outputting, by the device and to an external device, a digital representation of the load current based on the digital sense current value.
