VID5 to

VID0

Intel Mode. Voltage IDentification Pins (also applies to VID6, VID7).

Internally pulled up by 25µA to 5V, connect to SGND to program a '0' or leave

floating to program a '1'.

They allow programming output voltage as specified in Table 6 and Table 7

according to VID_SEL status. OVP and UVP protection comes as a

consequence of the programmed code (See Table 11).

AMD Mode. Voltage IDentification Pins.

Internally pulled down by 12.5µA, leave floating to program a '0' while pull up to

more than 1.4V to program a '1'.

They allow programming the output voltage as specified in Table 9 (VID7

doesn’t care). OVP and UVP protection comes as a consequence of the

programmed code (See Table 11).

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 5V (typ), if not used it

46

SS_END/ can be left floating.

PGOOD 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.

47 VR_HOT Thermal Monitoring Output enabled if Vcc > UVLOVCC.

See “Thermal monitor” Section for details and typical connections.

Voltage Regulator FAN. Over Temperature Warning Signal.

Open Drain Output, set free when TM overcomes the Warning Threshold.

48 VR_FAN Thermal Monitoring Output enabled if Vcc > UVLOVCC.

See “Thermal monitor” Section for details and typical connections.

Thermal Monitor Input.

TM

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.

Operation.

Channel 2 LS Driver Output.A small series resistor helps in reducing device-
