Current Excursion Protection (CEP)

This power management is a Processor integrated detector that senses when the Processor load current exceeds a preset threshold by monitoring for a Processor power domain voltage droop at the Processor power domain IMVPVR sense point. The Processor compares the IMVPVR output voltage with a preset threshold voltage (VTRIP) and when the IMVPVR output voltage is equal to or less than VTRIP, the Processor internally throttles itself to reduce the Processor load current and the power.

IMVP9.2 VRs enhance the CEP detector by adding a cycle by cycle current limiting feature where the IMVPVR quickly enters cycle by cycle current limit (becomes a current source) with the VR output current limited to a preset value (ITRIP) as set in the ICC_​limit register.
