PIP8000FHN
Digital power supervisor
ENABLE
12
O
A default but congurable pin dedicated to controlling the
on/off operation of the power train. May be set either
HIGH or LOW to enable.
RXD_ALERT
13
O
TXD
14
O
FAN_CONTROL2
15
O
User congurable active HIGH/LOW fan 1 on off.
FAN_CONTROL1
16
O
User congurable active HIGH/LOW fan 2 on off.
VDD
17
This is the power supply for normal operation as well as
Idle mode and Power-down mode.
GPIO
18
I/O
General Purpose Input/Output
User_A_D
19
I
Readable User A/D. Coefcients can be set for a
particular calibration/scale factor conguration.
TEMP1
20
I
Common analog temperature sensors connection, the
output of which is typically 25 mV /
°C. Coefcients can be
set for a particular calibration/scale factor conguration.
SAMPLE_IIN
21
I
Current sense amplier connection. Coefcients can be
set for a particular calibration/scale factor conguration.
SAMPLE_VIN
22
I
Connection for either directly to VIN if less than VDD or
through a resistor divider if higher than VDD. Coefcients
can be set for a particular calibration/scale factor
conguration.
VOUT_TRIM
23
O
This is a 20 kHz PWM square wave with a duty cycle that
is directly controlled by the PMBus Vout command. This
waveform is externally integrated to develop a DC level,
buffered, and then driven through a series scaling resistor
to become a current source into the analog controller
voltage feedback pin, which then changes the output
voltage of the power train. The scaling resistor can scale
the duty cycle change at pin 23 so that the power train
output voltage may be varied from V to mV. Coefcients
can be set for a particular calibration/scale factor
conguration.
FAN_SPEED1,
FAN_SPEED2
24, 25
I
Read-only pins connected as a 16-bit counter and used to
count fan RPM in certain applications. This requires fans
with three-pin wiring.
TEMP2
26
I
See pin 20, TEMP1.
SAMPLE_IOUT
27
I
Current sense amp connection. Coefcients can be set
for a particular calibration/scale factor conguration.
SAMPLE_VOUT
28
I
Connected either directly to Vo if less than VDD or through
a resistor divider if higher than VDD. Coefcients can be
set for a particular calibration/scale factor conguration.
