Function

Typical Connection

No Connect

Not connected. May be left floating, connected to GND or VDD.

VDD

Positive Supply Voltage Input

DC Voltage from 3.0 V to 3.6 V. VDD should be bypassed with

a 0.1µF capacitor in parallel with 100pF. The 100pF 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.

No Connect

Not connected. May be left floating, connected to GND or VDD.

No Connect

Not connected. May be left floating, connected to GND or VDD.

−

Diode Return Current Sink

To all Diode Cathodes. Common D- pin for all two remote

diodes.

D2+

Diode Current Source

To 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 perfomance in noisy systems. Float this pin if this

thermal diode is not used.

D1+

Diode Current Source

To 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 perfomance in noisy systems. Float this pin if this

thermal diode is not used.

GND

Power Supply Ground

System low noise ground.

Digital Input

SMBus slave address select pin. Selects one of three

addresses. Can be tied to VDD, GND, or to the middle of a

resistor divider connected between VDD and GND.

TCRIT1

Digital Output, Open-Drain

Critical temperature output 1. Requires pull-up resistor. Active

"LOW".

TCRIT2

Digital Output, Open-Drain

Critical temperature output 2. Requires pull-up resistor. Active

"LOW".

SMBDAT

SMBus Bi-Directional Data Line, From and to Controller; may require an external pull-up resistor

Open-Drain Output

SMBCLK

SMBus Clock Input

From Controller; may require an external pull-up resistor

TCRIT3

Digital Output, Open-Drain

Critical temperature output 3. Requires pull-up resistor. Active

"LOW".

N/A

Thermal pad

Connect the thermal pad to GND.
