Low power solutions can be provided in a serial bus system with a logic controller circuit. The logic controller circuit can include analog circuitry that includes a plurality of analog components and trimming circuitry for configuring the analog components. Digital circuitry can be configured to switch between an active mode and a hibernation mode, wherein the hibernation mode consumes less current than the active mode. A voltage regulator circuit can be configured to generate a regulated voltage from a supply voltage. A reset generation circuit can be configured to determine that the supply voltage has reached a first threshold voltage level and enable the voltage regulator circuit. When the regulated voltage has reached a second threshold voltage level and the supply voltage has reached a third threshold voltage level, the digital circuitry can be switched to the active mode.

A protocol can specifie a power-sourcing voltage range that indicates power sourcing capabilities. Additional power sourcing capabilities can be communicated using voltage variations within the power-sourcing voltage range. A power-sourcing device can provide power to an external power-sinking device over a wired connection containing a plurality of wires. A voltage control circuit can be configured to drive a voltage over a wire of the plurality of wires. Processing circuitry can communicate, using the voltage control circuit, first power-sourcing capabilities to the external power-sinking device by setting the voltage over the wire to a value within the power-sourcing voltage range. The processing circuitry can also communicate, using the voltage control circuit, the additional power sourcing capabilities of the power-sourcing device using voltage variations on the wire, the voltage variations maintaining voltage on the wire within the power-sourcing voltage range.

A system including a device that is configured to communicate current sourcing capabilities to an external power source over a wired connection containing a plurality of wires. The device includes a power supply circuit configured to provide operating power for the device. A first pull-down circuit is configured to provide a pull-down for a particular wire of the wired connection using a first resistive element that is actively trimmed using the operating power. A second pull-down circuit includes at least one transistor that, in the absence of the operating power, is configured to enable a current path, in response to a gate voltage generated from a voltage on the particular wire, between the particular wire and a second resistive element.
