Maxim's MAX6686 is a dual, remote-junction temperature switch that monitors high and low alarms and protects processors from overheating.
The MAX6686 measures the temperature of a P-N junction in an external IC with 1,5°C accuracy, according to the manufacturer. The local temperature switch has a pin-programmable temperature threshold adjustable in 5°C increments. Two trip-threshold temperature ranges, +40°C to +80°C and +75°C to +115°C, are available.
The upper temperature limit is factory set at either +120°C or +125°C and is associated with a separate logic output. Typically, the upper limit is used for system shutdown and the lower limit is used for clock throttling, warning, or fan control. The device minimises false alarms by integrating and oversampling the diode voltage. Built-in hysteresis prevents output chattering when the measured temperature is close to the threshold temperature.
The MAX6686 is available in a tiny 8-pin microMAX package and is specified for the -40°C to +125°C temperature range. It operates from 3 to 5,5 V with a 200 µA supply current.
