8 Output Protection
These are features built into the VRD to prevent damage to itself, the processor, and other system
components.
8.1 Over-Voltage Protection (OVP) (PROPOSED)
An OVP circuit should monitor the output for an over-voltage condition. If the output is more
than 200 mV above the maximum VID level, the VRD should shut off the Vcc supply to the
processor.
8.2 Over-Current Protection (OCP) (PROPOSED)
The VRD must be capable of withstanding a continuous, abnormally low resistance on the output
without overstressing the voltage regulator. Output current under this condition must be limited to
avoid component damage and violation of the VRD thermal specifications (see Section 5).
