Abstract: Multiple power management integrated circuits (PMICs) may perform communication and power sequence operation coordination between the multiple PMICs through a communication interface connected to two signal lines using a dual pin interface. The multiple PMICs include a main PMIC configured to communicate with at least one application processor through a system interface and at least one sub-PMIC configured to communicate with the main PMIC through the communication interface. A first signal line uses a single bidirectional signaling scheme, and a power status signal PSTATUS is exchanged between the main PMIC and the at least one sub-PMIC through the first signal line. A second signal line uses a single unidirectional signaling scheme, and a power sequence control signal PIF is transmitted from the main PMIC to the at least one sub-PMIC through the second signal line.

Abstract: A system on chip (SoC) includes a first core and a second core, first and second power gating switches, and a first power switch. The first power gating switch is arranged between the first core and a first power rail that receives a first voltage, and is selectively turned on in response to a first power gating signal. The second power gating switch is arranged between the second core and a second power rail that receives a second voltage, and is selectively turned on in response to a second power gating signal. The first power switch is arranged between the first power rail and the second power rail, and is selectively turned on in response to a first power control signal to connect the first power gating switch or the second power gating switch both the first power rail and the second power rail.
