Description

The THMC10 is a dual digital temperature monitor with under/overtemperature alerts intended for use in personal computer systems or any other system requiring local as well as remote temperature monitoring and management (e.g., servers and workstations). The device may be used in smart battery applications and memory modules. The device is designed to measure the temperature on a microprocessor using a diode-connected transistor on the microprocessor die, such as the one present on the Intel® Pentium® II, III, and the Sun® UltraSPARCTM. The device may also be used with a low-cost, diode-connected, discrete transistor, such as a 2N3904 or 2N3906, for remote temperature sensing applications.

The THMC10 uses a two-current measurement technique on a single diode-connected transistor that cancels the absolute value of the remote transistor's VBE; therefore, no calibration is needed.
