Abstract
Apparatus for managing power in a data storage device, such as a solid state drive (SSD). In some embodiments, an energy management circuit supplies electrical power to a non-volatile memory (NVM). The energy management circuit has cascaded first and second E-Fuse switch circuits each with an input terminal and an output terminal. The second E-Fuse switch circuit receives input power from the first E-Fuse switch circuit used as a rail voltage for the device. The second E-Fuse switch circuit is configured to monitor the rail voltage, deactivate the first E-Fuse switch circuit responsive to the rail voltage falling below a predetermined threshold, and supply backup power to the device from a backup power source.
