What is PMU (PMIC) PMU (Power Management Unit) is a power management unit, a highly integrated power management solution for portable applications, that is, the traditional Discrete power management chips, for example, low-voltage differential linear voltage regulators (LVS) and DC/DC converters (DC/DC), but now they

, these power supplies can also be synchronized with the function on and off these supply voltages to support voltage domain switching. PMU is usually customized with the main chip binding. Because it's going to fit the CPU's power-up sequence. The power-up sequence of some voltages and the time interval between them have a succession relationship and a time requirement. The mask
