Abstract: Systems and techniques for power delivery to an electronic device using multiple power management integrated circuits (PMICs) are described herein. The systems and techniques provide for two signal connections between each of the PMICs to sync transition signals on a first line and provide faults to interrupt operations on a second line. The PMICs are connected to an electronic device that commands power transitions for voltage rails from the PMICs with the commands received over I2C communication from the electronic device.
