Abstract: An output driver is provided. The output driver includes: a pull-up driver connected between an output power supply voltage and an output node, and configured to pull up a voltage at the output node based on a pull-up driving signal and a pull-up reference voltage; a pull-down driver connected between the output node and a ground voltage, and configured to pull down the voltage at the output node based on a pull-down driving signal and a pull-down reference voltage; and a reference voltage compensation circuit configured to perform a short operation during transitions of the pull-up driving signal and the pull-down driving signal, wherein the short operation includes electrically connecting any one or any combination of the pull-up reference voltage to the ground voltage, and the pull-down reference voltage to the output power supply voltage.

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 context hub receives and processes data from multiple sensors. An operation method of the context hub includes identifying a pattern of context data input to the context hub from at least one of the sensors, determining a dynamic voltage-frequency scaling (DVFS) level corresponding to the identified pattern of the context data, and processing, at the context hub, the context data by using a clock signal or a driving voltage corresponding to the determined DVFS level.
