The is a 5-channel precision temperature monitor with beta compensation in 16 pin TQFN package. This precision multichannel temperature sensor monitors its own temperature and temperatures of up to four external diode connected transistors. All temperature channels have programmable alert thresholds. Channels 1 and 4 also have programmable overtemperature thresholds. When the measured temperature of a channel exceeds 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 status register. The 2-wire serial interface supports standard system management bus SMBus protocols write byte, read byte, send byte and receive byte for reading temperature data and programming alarm thresholds.
