MAX6699 Overview

5-Channel Precision Temperature Monitor

19-3859; Rev 0; 12/05
5-Channel Precision Temperature Monitor
General Description
The MAX6699 precision multichannel temperature sen-
sor monitors its own temperature and the temperatures
of up to four external diode-connected transistors.
All temperature channels have programmable alert
thresholds. Channels 1 and 4 also have programmable
overtemperature thresholds. When the measured tem-
perature of a channel exceeds the respective thresh-
old, a status bit is set in one of the status registers. Two
open-drain outputs,
OVERT
and
ALERT,
assert corre-
sponding to these bits in the status register.
The 2-wire serial interface supports the standard system
management bus (SMBus™) protocols: write byte, read
byte, send byte, and receive byte for reading the tem-
perature data and programming the alarm thresholds.
The MAX6699 is specified for an operating temperature
range of -40°C to +125°C and is available in 16-pin
QSOP and 16-pin TSSOP packages.
