MAX6689 - 7-Channel Precision Temperature Monitor

Description

The MAX6689 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.

www.DataSheet4U.com 19-0567; Rev 0; 5/06 7-Channel Precision Temperature Monitor General Description The MAX6689 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 and ALERT, assert corresponding to these bits in the status register.
