Vin_Good - Intel S7000FC4UR Technical Product Specification

Intel® Server System S7000FC4UR TPS Power Distribution Board
In the event AC main power is lost, or a fan has failed, this signal must be driven low at least
1ms before any of the outputs go out of regulation.
The output will be an open collector/drain. It will be capable of driving the output below 0.4V
with a load of 4mA. The output will have an internal pull-up resistor of 1K between the output
and +3.3V standby. The pull-up will be connected to the anode side of the +3.3V standby
OR'ing diode.

This output also goes to I C port P5.

VIN_GOOD

This signal will be asserted, driven high, by the power supply to indicate that the input voltage
meets the minimum requirements of the input voltage range. Within 12ms after falling outside
the input voltage requirements, the output must be driven low.
