GENERAL DESCRIPTION

The TMP01 is a temperature sensor that 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 band gap 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 tempera-

ture trip points and generate an open-collector output signal

when one of their respective thresholds has been exceeded.

*Protected by U.S. Patent No. 5,195,827.

Hysteresis is also programmed by the external resistor chain and

is determined by the total current drawn out of the 2.5 V refer-

ence. 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 conjunc-

tion with production laser trimming to maintain a temperature

accuracy of ±1°C (typical) 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 low-cost 8-pin epoxy mini-DIP and

SO (small outline) packages.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

the TMP01 features proprietary ESD protection circuitry, permanent damage may occur on

devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are

recommended to avoid performance degradation or loss of functionality.

GENERAL DESCRIPTION

The TMP01 is a 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 accurate, temperature

compensated, band gap-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 Applica-

tions 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 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

VREF

) determines the

magnitude of the temperature hysteresis band. The open collector

outputs of the comparators can be used to control a wide variety

of devices.
