Intel mode. Voltage identification pins (also applies to VID6, VID7).
Internally pulled up by 25 µA to 5 V, connect to SGND to program a '0' or leave
floating to program a '1'.
They allow programming output voltage as specified in
according to VID_SEL status. OVP and UVP protection comes as a
consequence of the programmed code
AMD mode. Voltage identification pins.
Internally pulled down by 12.5 µA, leave floating to program a '0' while pull up to
more than 1.4 V to program a '1'.
They allow programming the output voltage as specified in
doesn’t care). OVP and UVP protection comes as a consequence of the
programmed code
Note. VID6 not used, need to be shorted to SGND.
SSEND - Intel mode. soft-start end signal.
Open drain output sets free after SS has finished and pulled low when
triggering any protection. Pull up to a voltage lower than 5 V (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 5 V (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 2 LS driver return path. Connect to power ground plane.
It must be connected to power ground plane also when using 2-phase
operation.
Channel 2 LS driver output. A small series resistor helps in reducing device-
dissipated power.
Leave floating when using 2 phase operation.
