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 (I
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.
