FUNCTION DESCRIPTION

Digital I/O. SMBus serial bi-directional data. Open-drain output.

Digital Input. SMBus serial clock input.

Ground. To be connected to system ground.

Power supply. Can be connected to +3.3 V standby power if monitoring in low power states is

required. This pin also serves as the analog input to monitor the VDD voltage level.

Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status

register (LSB bit).

Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status register.

Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status register.

Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status register.

Analog/Digital Input. This pin is connected to the negative terminal of the remote temperature sensor for

analog input. If this pin is held high at power-up, for digital input, it enables the NAND-TREE test mode.

Analog Input. This pin is connected to the positive terminal of the remote temperature sensor.

Analog/Digital Input. Defaults at power-up to analog input for monitoring the +12 V supply. This pin is

programmable to be a digital input for voltage ID readouts from the processor. Its state is read into

the VID4 status register.

Analog Input. For monitoring the +5 V supply.

Analog Input. For monitoring the +3.3 V supply.

Analog Input. For monitoring the +2.5 V supply.

Analog Input. For monitoring the processor voltage supply (0 to 3.0 V)

Digital I/O. At power-up, the logic input of this pin defines the LSB bit of the device slave address.

This pin can be configured to give a low pulse reset output of 20ms minimum. This pin also functions

as the output in the NAND–TREE test mode.
