Pin Description
Pin Number Pin Name Description Typical Connection
1, 10, 13, 14 NC No Connect May be tied to V+, GND or left floating. Do
not tie active signals to pin 10.
2 GND Ground System ground
3 V+/+3.3V_SBY Positive power supply pin as well
as a +3.3V voltage monitor
Connected system 3.3 V standby power and
to a 0.1 µF bypass capacitor in parallel with
100 pF. A bulk capacitance of approximately
10 µF needs to be in the near vicinity of the
LM41.
4 SWD SensorPath Bus line; Open-drain
output
Super I/O, Pull-up resistor, 1.6k
5 ADD Digital input - device number select
input for the serial bus device
number
Pull-up to 3.3 V or pull-down to GND resistor,
10k; must never be left floating
6 +1.2V +1.2V voltage monitoring input with
scaling resistors
Processor core voltage to be monitored
7 +2.5V +2.5V voltage monitoring input with
scaling resistors
Power supply voltage to be monitored
8 D- Thermal diode analog voltage
output and negative monitoring
input
Remote Thermal Diode cathode
(THERM_DC) - Can be connected to a CPU
or thermal diode, an MMBT3904 or a GPU
thermal diode. A 100 pF capacitor should be
connected between respective D- and D+ for
noise filtering.
9 D+ Thermal diode analog current
output and positive monitoring input
Remote Thermal Diode anode (THERM_DA) -
Can be connected to a CPU or thermal diode,
an MMBT3904 or a GPU thermal diode. A
100 pF capacitor should be connected
between respective D- and D+ for noise
filtering.
11 +5V +5V voltage monitoring input with
scaling resistors
Power supply voltage to be monitored
12 +12V +12V voltage monitoring input with
scaling resistors
Power supply voltage to be monitored
