Pin settings
11/70
46
SS_END/
PGOOD
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.
47
VR_HOT
Voltage Regulator HOT. Over Temperature Alarm Signal.
Open Drain Output, set free when TM overcomes the Alarm Threshold.
Thermal Monitoring Output enabled if Vcc > UVLOVCC.
See “Thermal monitor” Section for details and typical connections.
48
VR_FAN
Voltage Regulator FAN. Over Temperature Warning Signal.
Open Drain Output, set free when TM overcomes the Warning Threshold.
Thermal Monitoring Output enabled if Vcc > UVLOVCC.
See “Thermal monitor” Section for details and typical connections.
49
TM
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.
See “Thermal monitor” Section for details and typical connections.
50
SGND
All the internal references are referred to this pin. Connect to the PCB Signal
Ground.
51
VCCDR4
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 1F MLCC cap
vs. PGND4.
52
LGATE4
Channel 4 LS Driver Output. A small series resistor helps in reducing device-
dissipated power.
53
PGND4
Channel 4 LS Driver return path. Connect to Power ground Plane.
54
PGND2
Channel 2 LS Driver return path. Connect to Power ground Plane.
55
LGATE2
Channel 2 LS Driver Output. A small series resistor helps in reducing device-
dissipated power.
56
VCCDR2
Channel 2 LS Driver Supply.
It must be connected to others VCCDRx pins.
LS Driver supply can range from 5Vbus up to 12Vbus, filter with 1F MLCC cap
vs. PGND2.
57
VCCDR3
Channel 3 LS Driver Supply.
It must be connected to others VCCDRx pins.
LS Driver supply can range from 5Vbus up to 12Vbus, filter with 1F MLCC cap
vs. PGND3.
58
LGATE3
Channel 3 LS Driver Output.A small series resistor helps in reducing device-
dissipated power.
59
