The MAX6697 / MAX6698
precision multichannel temperature sensor
monitors its own temperature and the temperatures of up to six external diode-connected transistors. 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, OVERT-bar and ALERT-bar, assert corresponding to these bits in the status register.
The 2-wire serial interface supports the standard system management bus (SMBusTM) protocols: write byte, read byte, send byte, and receive byte for reading the temperature data and programming the alarm thresholds.
The MAX6697 is specified for an operating temperature range of -40°C to +125°C and is available in 20-pin QSOP and 20-pin TSSOP packages.
