1°C Accurate Remote/Local Temperature

Sensor with SMBus Serial Interface

General Description

Features

The MAX6654^†is a precise digital thermometer that

reports the temperature of both a remote P-N junction

and its own die. The remote junction can be a diode-con-

nected transistor—typically a low-cost, easily mounted

2N3904 NPN type or 2N3906 PNP type—that replaces

conventional thermistors or thermocouples. Remote

accuracy is ±±1° for multiple transistor manufacturers,

with no calibration needed. The remote junction can also

be a common-collector PNP, such as a substrate PNP of

a microprocessor (µP).

The 2-wire serial interface accepts standard System

Management Bus (SMBus)^TM, Write Byte, Read Byte,

Send Byte, and Receive Byte commands to program the

alarm thresholds and to read temperature data.

Measurements can be done automatically and

autonomously, with the conversion rate programmed by

the user, or programmed to operate in a single-shot

mode. The adjustable conversion rate allows the user to

optimize supply current and temperature update rate to

match system needs. When the conversion rate is faster

than ±Hz, the conversion results are available as a 7-bit-

plus-sign byte with a ±1° LSB. When the conversion rate

is ±Hz or slower, the MAX6654 enters the extended

mode. In this mode, 3 additional bits of temperature data

are available in the extended resolution register, provid-

ing ±0-bit-plus-sign resolution with a 0.±251° LSB.

Single-shot conversions also have 0.±251° per LSB reso-

lution when the conversion rate is ±Hz or slower.

A parasitic resistance cancellation (PR°) mode can also

be invoked for conversion rates of ±Hz or slower by set-

ting bit 4 of the configuration register to ±. In PR° mode,

the effect of series resistance on the leads of the external

diode is canceled. The ±±-bit conversion in PR° mode is

performed in <500ms and is disabled for conversion

rates faster than ±Hz. The one-shot conversion is also ±±

bits in <500ms.

The MAX6654 default low-temperature measurement
