CAUTION 1. Stresses above those listed under “Absolute Maximum Rat- ings” may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to the above maximum rating conditions for extended periods may affect device reliability. 2. Digital inputs and outputs are protected, however, permanent damage may occur on unprotected units from high energy electrostatic fields. Keep units in conductive foam or packag- ing at all times until ready to use. Use proper antistatic han- dling procedures. 3. Remove power before inserting or removing units from their sockets.

GENERAL DESCRIPTION The TMP01 is a very linear voltage-output temperature sensor, with a window comparator that can be programmed by the user to activate one of two open-collector outputs when a predeter- mined temperature setpoint voltage has been exceeded. A low drift voltage reference is available for setpoint programming. The temperature sensor is basically a very accurately tempera- ture compensated, bandgap-type voltage reference with a buff- ered output voltage proportional to absolute temperature (VPTAT), accurately trimmed to a scale factor of 5 mV/K. See the Applications Information following. The low drift 2.5 V reference output VREF is easily divided ex- ternally with fixed resistors or potentiometers to accurately es- tablish the programmed heat/cool setpoints, independent of temperature. Alternatively, the setpoint voltages can be supplied by other ground referenced voltage sources such as user- programmed DACs or controllers. The high and low setpoint voltages are compared to the temperature sensor voltage, thus creating a two-temperature thermostat function. In addition, the total output current of the reference (IVREF) determines the magnitude of the temperature hysteresis band. The open collec- tor outputs of the comparators can be used to control a wide va- riety of devices.
