6.1Voltage Regulator Ready (VR_Ready) - REQUIRED

The VRM/EVRD VR_Ready signal is an output signal that indicates the start-up sequence is complete and the output voltage has moved to the programmed VID value. This signal will be used for start-up sequencing for other voltage regulators, clocks, and microprocessor reset. This signal is not a representation of the accuracy of the DC output to its VID value.

The platform VR_Ready signal(s) will be connected to logic to assert CPU or system PWRGD. The value of the resistor and the pull-up voltage will be determined by the circuitry on the baseboard that is receiving this signal. Typically a 1 kΩ pull to 3.3 V is used. This signal should not be de-asserted during dynamic VID operation. It should remain asserted during normal DC-DC operating conditions and only de-assert for fault shutdown conditions. It will be an open-collector/drain or equivalent signal. The pull-up resistor and voltage source will be located on the baseboard. Table 6-1shows the VR_Ready pin specification.

6.2Voltage Regulator Hot (VR_hot#) - PROPOSED

The VRM/EVRD VR_hot# signal is an output signal that is asserted low when a thermal event is detected in the converter. Assertion of this signal will be used by the system to minimize damage to the converter due to the thermal conditions. Table 6-2shows the VR_hot# signal specification. This signal will be an open-collector/drain or equivalent signal and needs to be pulled up to an appropriate voltage through a pull-up resistor on the baseboard. A typical implementation would be a 50 Ω ±5% resistor pulled up to

1.1V/1.2 V. For platforms using a voltage higher than 1.1 V /1.2 V, a voltage level translation is required. Processors do not tolerate such voltage levels directly. Consult the appropriate PDG.

Each customer is responsible for identifying maximum temperature specifications for all components in the VRM/EVRD design and ensuring that these specifications are not violated while continuously drawing specified Icc (TDC) levels. In the occurrence of a thermal event, a thermal sense circuit may assert the processor’s FORCEPR# signal immediately prior to exceeding maximum VRM, baseboard, and/or component thermal ratings to prevent heat damage. The assertion may be made through direct connection
