DESCRIPTION
Thermistor input to VR_HOT_L circuit to monitor Northbridge VR temperature.
Northbridge output current monitor. A current proportional to the Northbridge VR output current is
sourced from this pin.
Serial VID clock input from the CPU processor master device.
Thermal indicator signal to AMD CPU. Thermal overload open drain output indicator active LOW.
Serial VID data bidirectional signal from the CPU processor master device to the VR.
VDDIO is the processor memory interface power rail and this pin serves as the reference to the controller
IC for this processor I/O signal level.
Serial VID Telemetry (SVT) data line input to the CPU from the controller IC. Telemetry and VID-on-the-fly
complete signal provided on from this pin.
Enable input. A high level logic on this pin enables both VRs.
System power good input. When this pin is high, the SVI 2 interface is active and the I 2 C protocol is
running. While this pin is low, the SVC and SVD input states determine the pre-PWROK metal VID. This
pin must be low prior to the ISL62771 PGOOD output going high per the AMD SVI 2.0 Controller
Guidelines.
Core output current monitor. A current proportional to the Core VR output current is sourced from this pin.
Thermistor input to VR_HOT_L circuit to monitor Core VR temperature.
Individual current sensing for Channel 2 of the Core VR. When ISEN2 is pulled to +5V, the controller
disables Channel 2, and the Core VR runs in single-phase mode.
