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 V
BE; therefore, no
calibration is needed. The second channel measures an on-chip temperature sensor which can
be used to monitor the ambient temperature in the THMC10's operating environment.
The THMC10 uses a two-wire, SMBus interface to report temperature in an 8-bit, 2s
complement format in °C. Under/overtemperature limits for both the on-chip and remote
temperature sensors are user programmable via the SMBus interface. The ALERT\ terminal
can be used as an interrupt or SMBus alert function to indicate under/overtemperature. The
STBY\ terminal and the start/stop bit in the SMBus interface allow the device to enter a low
current standby mode (typically <10 uA).
The THMC10 also provides diagnostics via the ALERT\ terminal and the SMBus interface
for an open remote sensor connection or if the sensor connection is shorted to V
DD.
