5 Output Protection
Output protection features are necessary to prevent damage to the VRD, the processor, and other
system components.
5.1 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.
5.2 Over-Current Protection (OCP) (PROPOSED)
The VRD should be capable of withstanding a continuous, abnormally low resistance on the
output without overstressing the voltage regulator. Output current under this condition should be
limited to avoid component damage and violation of the VRD thermal specifications (see Section
2.5).
