Typical Application

PIN DESCRIPTIONS

Label Pin # Function Typical Connection

floating, unconnected Left floating. PC board traces may be routed through the pads

NC 1, 5

for these pins. No restrictions applied.

2 Positive Supply Voltage Input DC Voltage from 3.0 V to 3.6 V

Diode Current Source To Diode Anode. Connected to remote discrete diode junction

D+ 3 or to the diode junction on a remote IC whose die temperature

is being sensed. When not used they should be left floating.

D− 4 Diode Return Current Sink To Diode Cathode. Must float when not used.

User-Set SMBus (I

C) Address Ground (Low, “0”), V

(High, “1”) or open (“TRI-LEVEL”)

ADD0–ADD1 10, 6

Inputs

GND 7, 8 Power Supply Ground Ground

Manufacturing test pins. Left floating. PC board traces may be routed through the pads

for these pins, although the components that drive these traces

NC 9, 13, 15

should share the same supply as the LM82 so that the

Absolute Maximum Rating, Voltage at Any Pin, is not violated.

C) Serial Bi- From and to Controller, Pull-Up Resistor

SMBData 12 Directional Data Line, open-

drain output

SMBCLK 14 SMBus (I

C) Clock Input From Controller, Pull-Up Resistor
