Typical Application

PIN DESCRIPTIONS

Label

Pin #

Function

Typical Connection

floating, unconnected

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

1, 5

for these pins. No restrictions applied.

VCC

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+

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

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

−

Diode Return Current Sink

To Diode Cathode. Must float when not used.

User-Set SMBus (I2C) Address

Ground (Low, “0”), VCC (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

9, 13, 15

should share the same supply as the LM82 so that the

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

INT

Interrupt Output, open-drain

Pull Up Resistor, Controller Interrupt or Alert Line

SMBus (I2C) Serial Bi-

From and to Controller, Pull-Up Resistor

SMBData

Directional Data Line, open-

drain output

SMBCLK

SMBus (I2C) Clock Input

From Controller, Pull-Up Resistor

Critical Temperature Alarm,

Pull Up Resistor, Controller Interrupt Line or System Shutdown

T_CRIT_A

open-drain output
