Abstract: A nonvolatile storage device includes a power management system with a power loss imminent (PLI) capacitor to provide backup energy in case system power is lost. The power management system includes a circuit with a charging path for the PLI capacitor that includes a series current-limiting circuit, and a diode coupled in parallel with the current-limiting circuit, the diode having a cathode coupled to the charging circuit and an anode to couple to the PLI capacitor.
