Abstract: In some examples, a circuit includes a sink/source mode detector configured to compare a voltage provided at the first I/O terminal of the circuit to a first reference signal; determine, responsive to the voltage provided at the first I/O terminal exceeding the first reference signal, that the circuit is in a source mode; determine, responsive to the voltage provided at the first I/O terminal not exceeding the first reference signal, that the circuit is in a sink mode; responsive to determining that the circuit is in the source mode and an input signal of the circuit has a value less than a second reference signal, control a first switch to form a first current path between a voltage supply terminal and the first I/O terminal of the circuit; and responsive to determining that the circuit is in the sink mode and the input signal has a value greater than the second reference signal, control a second switch to form a second current path between a ground terminal and the first I/O terminal of the circuit.

Abstract: A circuit includes a supply circuit having an input and an output. The supply circuit includes: a capacitor having a first terminal and a second terminal, the first terminal of the capacitor coupled to the output of the supply circuit; a switch having a first terminal, a second terminal, and a control terminal, the first terminal of the switch coupled to the input of the supply circuit, the second terminal of the switch coupled to the output of the supply circuit; and a controller coupled to the control terminal of the switch. The controller is configured to: turn on the switch responsive to a first supply voltage level at the input of the supply circuit; and turn off the switch responsive to a second supply voltage level at the input of the supply circuit.

Abstract: In an example, a method of operating a repeater having an isolation barrier to isolate a host side of the repeater from a peripheral side of the repeater, the repeater operable to be coupled to a universal serial bus (USB), includes causing the host side to enter into a suspend mode. The method also includes, responsive to entering the suspend mode, disabling a host isolation transceiver at the host side. The method includes periodically enabling the host isolation transceiver to transmit a data signal from the host side to the peripheral side. The method includes exiting the suspend mode. The method also includes enabling the host isolation transceiver.

Abstract: A system includes a switching converter, an input voltage source coupled to an input of the switching converter, and a load coupled to an output of the switching converter. The system also includes a load sense circuit coupled to the load and configured to provide a load sense signal. The system also includes an oscillator coupled to the switching converter and configured to provide a spread spectrum modulated (SSM) clock signal to the switching converter, wherein a frequency of the SSM clock signal varies as a function of the load sense signal.
