EVALUATION KIT AVAILABLE

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.
