Description

The THMC50 is a local/remote temperature monitor with two voltage supervisor circuits and an 8-bit, 0-V to 2.5-V DAC designed for temperature monitoring and fan control via a two-wire SMBus serial interface. The THMC50 is intended for use in personal computer applications according to the Advanced Configuration and Power Interface (ACPI) thermal model. The device is also suitable for use in network routers and hubs, office equipment, telephone switching networks, industrial control applications, and any other application requiring temperature monitoring, fan speed control, and two 3.3-V supply voltage supervisors.

Temperature data is reported in a 2s complement, 8-bit binary format. The local temperature sensor can be used to monitor the ambient temperature, while a remote thermal diode, such as the one present on the Intel® Pentium® II, III, and the Sun® UltraSPARCTM microprocessors, can be used to monitor the actual CPU die temperature.
