?癈 Accurate 8-Channel Temperature Sensor

MAX6581

EVALUATION KIT AVAILABLE

19-5260; Rev 1; 2/13

Ordering Information/Selector Guide

General Description

The MAX6581 precision multichannel temperature

sensor monitors its own temperature and the tempera-

tures of up to seven external diode-connected transis-

tors. All temperature channels have programmable alert

and overtemperature thresholds. When the measured

temperature of a channel crosses the respective thresh-

old, a status bit is set in one of the status registers. Two

open-drain alarm outputs (ALERT and OVERT) assert

corresponding to these bits in the status register(s).

Resistance cancellation is available for all channels and

compensates for high series resistance in circuit-board

traces and thermal diodes.

The 2-wire serial interface accepts SMBus protocols

(write byte, read byte, send byte, and receive byte) for

reading the temperature data and programming the

alarm thresholds.

The MAX6581 is specified for an operating temperature

range of -40NC to +125NC and is available in a 24-pin,

4mm x 4mm thin QFN package with an exposed pad.
