A new precision five-channel temperature sensor in a small 16-pin QSOP or TSSOP package from Maxim is claimed to be the world's highest accuracy, programmable, five-channel temperature monitor. The MAX6699 accurately measures its own temperature and the temperature of up to four external locations with 1°C temperature accuracy. The four remote locations can be CPUs, GPUs, memory devices, and other important locations. It also allows the user to program the temperature threshold of alarm outputs. Designed for user flexibility, these outputs can serve as an interrupt, or can be connected to a system fan or other thermal management circuitry. The MAX6699 communicates through an SMBus interface, operates from 3 to 5 V and consumes only 500 μA (3 μA in standby). It is specified over -40 to 125°C.
