Description
No Connect
Ground
Positive power supply pin as well
as a +3.3V voltage monitor
Typical Connection
May be tied to V+, GND or left floating
System ground
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
LM40.

Remote Thermal Diode cathode
(THERM_DC) - Diode 1 should always be
connected to the processor thermal diode.
Diode 2 may be connected to an MMBT3904
or GPU thermal diode. A 100 pF capacitor
should be connected between respective D-
and D+ for noise filtering.
Remote Thermal Diode anode (THERM_DA) -
Diode 1 should always be connected to the
processor thermal diode. Diode 2 may be
connected to an MMBT3904 or GPU thermal
diode. A 100 pF capacitor should be
connected between respective D- and D+ for
