The MAX6698 precision multichannel temperature sensor
monitors its own temperature, the temperatures of
three external diode-connected transistors, and the
temperatures of three thermistors. All temperature
channels have programmable alert thresholds.
Channels 1, 4, 5, and 6 also have programmable overtemperature
thresholds. When the measured temperature
of a channel exceeds the respective threshold, a
status bit is set in one of the status registers. Two open-drain
outputs, active-low OVERT and active-low ALERT, assert corresponding
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 temperature
data and programming the alarm thresholds.
The MAX6698 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.
