Pin functions
SSEND - Intel Mode. Soft Start END Signal.
Open Drain Output set free after SS has finished and pulled low when triggering
any protection. Pull up to a voltage lower than 5V (typ), if not used it can be left
floating.
PGOOD - AMD Mode.
Open Drain Output set free after SS has finished and pulled low when VSEN is
lower than the relative threshold. Pull up to a voltage lower than 5V (typ), if not
used it can be left floating.
Voltage Regulator HOT. Over Temperature Alarm Signal.
Open Drain Output, set free when TM overcomes the Alarm Threshold.
Thermal Monitoring Output enabled if Vcc > UVLO
See “Thermal monitor” Section
Voltage Regulator FAN. Over Temperature Warning Signal.
Open Drain Output, set free when TM overcomes the Warning Threshold.
Thermal Monitoring Output enabled if Vcc > UVLO
See “Thermal monitor” Section
Thermal Monitor Input.
It senses the regulator temperature through apposite network and drives
VR_FAN and VR_HOT accordingly.Short TM pin to SGND if not used.

Ground.
Channel 4 LS Driver Supply.
It must be connected to others VCCDRx pins.
LS Driver supply can range from 5Vbus up to 12Vbus, filter with 1µF MLCC cap
vs. PGND4.
Channel 4 LS Driver Output. A small series resistor helps in reducing device-
dissipated power.
Channel 4 LS Driver return path. Connect to Power ground Plane.
Channel 2 LS Driver return path. Connect to Power ground Plane.
Channel 2 LS Driver Output. A small series resistor helps in reducing device-
dissipated power.
