Temperature Sensor Probe

The ADM10321 is a dual-channel digital thermometer and under/overtemperature alarm intended for use in PCs and thermal management systems. The device can measure the temperature of a remote thermal diode, which can be located on the processor die or can be a discrete device (2N3904/06), accurate to 1oC. A novel measurement technique cancels out the absolute value of the transistorR^s base emitter voltage so that no calibration is required. The ADM1032 also measures its ambient temperature. The ADM1032 communicates over a 2-wire serial interface compatible with system management bus (SMBus) standards. Under/overtemperature limits can be programmed into the device over the Sm Bus, and an ALERT output signals when the on-chip or remote temperature measurement is out of range. This output can be used as an interrupt or as a Sm Bus alert. The THERM output is a comparator output that allows CPU clock throttling or on/off control of a cooling fan. An ADM1032-1 and ADM1032-2 are available. The difference between the ADM1032 and theADM1032-1 is the default value of the external THERM limit. The ADM1032-2 has a different Sm Bus address. The Sm Bus address of theADM1032-2 is 0x4D. 1 Patents 5,982,221; 6,097,239; 6,133,753; 6,169,442; 5,867,012.

The TCN75 is a serially programmable temperature sensor that notifies the host controller when ambient temperature exceeds a user programmed set point. Hysteresis is also programmable. The INT/CMPTR output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt. Communication with the TCN75 is accomplished via a two-wire bus that is compatible with industry standard protocols. This permits reading the current temperature, programming the set point and hysteresis, and configuring the device. The TCN75 powers up in Comparator mode with adefault set point of 80oC with 5oC hysteresis. Defaults allow independent operation as a stand-alone thermostat. A shutdown command may be sent via the 2-wire bus to activate the low-power Standby mode. Address selection inputs allow up to eight TCN75s to share the same 2-wire bus for multi zone monitoring. All registers can be read by the host and the INT/CMPTR output's polarity is user programmable. Both polled and interrupt driven systems are easily accommodated. Small physical size, low installed cost, and ease-of-use make the TCN75 an ideal choice for implementing sophisticated system management schemes.
