GENERAL DESCRIPTION

The TMP01 is a temperature sensor which generates a voltage
output proportional to absolute temperature and a control signal
from one of two outputs when the device is either above or
below a specific temperature range. Both the high/low tempera­ture trip points and hysteresis (overshoot) band are determined
by user-selected external resistors. For high volume production,
these resistors are available on-board.

The TMP01 consists of a bandgap voltage reference combined
with a pair of matched comparators. The reference provides
both a constant 2.5 V output and a voltage proportional to abso­lute temperature (VPTAT) which has a precise temperature co­efficient of 5 mV/K and is 1.49 V (nominal) at +25°C. The
comparators compare VPTAT with the externally set tempera­ture trip points and generate an open-collector output signal
when one of their respective thresholds has been exceeded.

FUNCTIONAL BLOCK DIAGRAM

Hysteresis is also programmed by the external resistor chain and
is determined by the total current drawn out of the 2.5 V refer­ence. This current is mirrored and used to generate a hysteresis
offset voltage of the appropriate polarity after a comparator has
been tripped. The comparators are connected in parallel, which
guarantees that there is no hysteresis overlap and eliminates
erratic transitions between adjacent trip zones.

The TMP01 utilizes proprietary thin-film resistors in conjunc­tion with production laser trimming to maintain a temperature
accuracy of ±1°C (typ) over the rated temperature range, with
excellent linearity. The open-collector outputs are capable of
sinking 20 mA, enabling the TMP01 to drive control relays di­rectly. Operating from a +5 V supply, quiescent current is only
500 µA (max).

The TMP01 is available in the low cost 8-pin epoxy mini-DIP
and SO (small outline) packages, and in die form.

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 packag­ing at all times until ready to use. Use proper antistatic han­dling 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 predeter­mined temperature setpoint voltage has been exceeded. A low
drift voltage reference is available for setpoint programming.

The temperature sensor is basically a very accurately tempera­ture compensated, bandgap-type voltage reference with a buff­ered 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 ex­ternally with fixed resistors or potentiometers to accurately es­tablish the programmed heat/cool setpoints, independent of
temperature. Alternatively, the setpoint voltages can be supplied
by other ground referenced voltage sources such as user­programmed 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

) determines the

VREF

magnitude of the temperature hysteresis band. The open collec­tor outputs of the comparators can be used to control a wide va­riety of devices.
