A Maintain Power Signature (MPS) Powered Device (PD) is described. In one or more implementations, the MPS device comprises a current sensor configured to sense current flowing from Power Sourcing Equipment (PSE) to the PD. The current sense based MPS device also comprises a current generator configured to sink electrical current to prevent the PSE from removing power to the PD. Thus, the electrical current comprises a current amplitude characteristic selected based upon MPS requirements of the PSE. In some implementations, the current is sunk to a ground. In other implementations, the current is sunk to a storage device, such as a storage device included with the PD and/or external to the PD.
