General Description

Features

The MAX6657/MAX6658/MAX6659 are precise, two-

channel digital temperature sensors. Each accurately

measures the temperature of its own die and one

remote PN junction, and reports the temperature in digi-

tal form on a 2-wire serial interface. The remote junction

can be a diode-connected transistor like the low-cost

NPN type 2N3904 or 2N3906 PNP type. The remote

junction can also be a common-collector PNP, such as

a substrate PNP of a microprocessor.

ꢀ Programmable Under/Overtemperature Alarms

The 2-wire serial interface accepts standard System

Management Bus (SMBus™) commands such as Write

Byte, Read Byte, Send Byte, and Receive Byte to read

the temperature data and program the alarm thresholds

and conversion rate. The MAX6657/MAX6658/

MAX6659 can function autonomously with a program-

mable conversion rate, which allows the control of sup-

ply current and temperature update rate to match

system needs. For conversion rates of 4Hz or less, the

temperature is represented in extended mode as 10

bits + sign with a resolution of 0.125°C. When the con-

version rate is faster than 4Hz, output data is 7 bits +

sign with a resolution of 1°C. The MAX6657/

MAX6658/MAX6659 also include an SMBus timeout

feature to enhance system reliability.

PACKAGE TEMP. RANGE

Remote accuracy is 1°C between +60°C and +100°C

with no calibration needed. The MAX6657 measures

temperatures from 0°C to +125°C and the MAX6658/

MAX6659 from -55°C to +125°C. The MAX6659 has the

added benefit of being able to select one of three

addresses through an address pin, and a second over-

temperature alarm pin for greater system reliability.
