1 / 18 page General Description The MAX6697 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 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.
