The Temp-Log 6 Click Board™ is a temperature sensing Click Board™, which features the MAX6642, a specifically designed IC, capable of measuring its own die temperature, as well as a temperature at a remote PN junction. This option makes Temp-Log 6 Click Board™ well-suited for monitoring the temperature of a CPU, GPU or FPGA, where the PN junction is typically a substrate PNP transistor on the die of the measured IC. Instead of measuring the PN junction of a specifically designed IC, the Temp-Log 6 Click Board™ can also use an external diode or a small-signal transistor. The MAX6642 can also report an ALERT signal if programmed temperature thresholds are exceeded.
