10/64
40 to
45
VID5 to
VID0
Intel mode. Voltage identification pins (also applies to VID6, VID7).
Internally pulled up by 25 A to 5 V, connect to SGND to program a '0' or leave
floating to program a '1'.
according to VID_SEL status. OVP and UVP protection comes as a
consequence of the programmed code (See Table 12).
AMD mode. Voltage identification pins.
Internally pulled down by 12.5 A, 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 Table 10 (VID7
doesn’t care). OVP and UVP protection comes as a consequence of the
programmed code (See Table 12).
Note. VID6 not used, need to be shorted to SGND.
46
SS_END/
PGOOD
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.
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
N.C.
Not internally connected.
52
N.C.
Not internally connected.
53
N.C.
Not internally connected.
54
PGND2
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.
55
LGATE2
Channel 2 LS driver output. A small series resistor helps in reducing device-
dissipated power.
Leave floating when using 2 phase operation.
