Abstract
The various implementations described herein include systems, methods and/or devices used to protect data in a storage device. In one aspect, a method includes (1) powering a power control processor (PCP) (also sometimes called a storage-level microcontroller) using a first input voltage, (2) while the PCP is powered using the first input voltage: (a) operating the PCP in a first mode, and (b) enabling charging of an energy storage device, (3) after achieving a predefined internal state, which includes the energy storage device charged to a predefined level, powering the PCP using a power supply voltage distinct from the first input voltage, and (4) while the PCP is powered using the power supply voltage, operating the PCP in a second mode, where the PCP operates at a higher performance level in the second mode than in the first mode.
