Abstract:
A data storage device (DSD) includes a power supply from a host and a charge storage element. A current transient is detected on the power supply from the host and it is determined whether the current transient exceeds a current threshold. When the current transient exceeds the current threshold, power is drawn from the charge storage element to reduce power drawn from the host.
