General Description
The MAX6689 precision multichannel temperature sen-
sor monitors its own temperature and the temperatures
of up to six external diode-connected transistors. All
temperature channels have programmable alert thresh-
olds. Channels 1, 4, 5, and 6 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 MAX6689 is specified for an operating temperature
range of -40癈 to +125癈 and is available in 20-pin
QSOP and TSSOP packages.
