Methods, systems, and devices for power arbitration for systems of electronic components are described. A system may include a power source, a signaling conductor coupled with a voltage source, and a set of electronic components. One or more of the electronic components may include respective circuitry coupled with the power source and a respective switching component (e.g., a transistor) coupled with the signaling conductor. In some implementations, an electronic component of the set may be configured to determine an operation of its respective circuitry that is associated with a power consumption from the power source. Based on such a determination, the electronic component may switch its respective switching component in accordance with an identifier associated with the electronic component, and determine whether to perform the operation based on monitoring a signal level of the signaling conductor during the switching.
