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.
