Function
Typical Connection
No Connect
Not connected. May be left floating, connected to GND or
V
DD
.
DC Voltage from 3.0V to 3.6V. V
DD
should be bypassed with
a 0.1 μF capacitor in parallel with 100 pF. The 100 pF
capacitor should be placed as close as possible to the power
supply pin. Noise should be kept below 200 mVp-p, a 10 μF
capacitor may be required to achieve this.
Fourth Diode Anode. Connected to remote discrete diode-
connected transistor junction or to the diode-connected
transistor junction on a remote IC whose die temperature is
being sensed. A capacitor is not required between D4+ and
D-. A 100 pF capacitor between D4+ and D- can be added
and may improve performance in noisy systems. Float this pin
if this thermal diode is not used.
Third Diode Anode. Connected to remote discrete diode-
connected transistor junction or to the diode-connected
transistor junction on a remote IC whose die temperature is
being sensed. A capacitor is not required between D3+ and
D-. A 100 pF capacitor between D3+ and D- can be added
and may improve performance in noisy systems. Float this pin
if this thermal diode is not used.
All Diode Cathodes. Common D- pin for all four remote
diodes.
Second Diode Anode. Connected to remote discrete diode-
connected transistor junction or to the diode-connected
transistor junction on a remote IC whose die temperature is
being sensed. A capacitor is not required between D2+ and
D-. A 100 pF capacitor between D2+ and D- can be added
and may improve performance in noisy systems. Float this pin
if this thermal diode is not used.
First Diode Anode. Connected to remote discrete diode-
connected transistor junction or to the diode-connected
transistor junction on a remote IC whose die temperature is
being sensed. A capacitor is not required between D1+ and
D-. A 100 pF capacitor between D1+ and D- can be added
and may improve performance in noisy systems. Float this pin
if this thermal diode is not used.
System low noise ground.
SMBus slave address select pin. Selects one of three
addresses. Can be tied to V
DD
, GND, or to the middle of a
resistor divider connected between V
DD
and GND.
Critical temperature output 1. Requires pull-up resistor. Active
"LOW".
Critical temperature output 2. Requires pull-up resistor. Active
"LOW".
From and to Controller; may require an external pull-up
resistor
