GENERAL DESCRIPTION

becomes active when the temperature goes higher than the

The ADT6501/ADT6502/ADT6503/ADT6504 are trip point

temperature switches available in a 5-lead SOT23 package. It

contains an internal band gap temperature sensor for local

temperature sensing. When the temperature crosses the trip

point setting, the logic output is activated. The ADT6501/

ADT6503 logic output is active low and open-drain. The

ADT6502/ADT6504 logic output is active high and push-pull.

The temperature is digitized to a resolution of +0.0625°C

(12 bit). The factory settings are 10°C apart starting from −45°C

to +15°C for the cold threshold models and from +35°C to

+115°C for the hot threshold models.

selected trip point temperature. The ADT6503 and ADT6504

are used for monitoring temperatures from −45°C to +15°C

only. Hence, the logic output pin becomes active when the

temperature goes lower than the selected trip point

temperature.

PRODUCT HIGHLIGHTS

0.5°C typical from −55°C to +125°C.

2. Factory threshold settings from −45°C to +115°C in 10°C

increments

These devices require no external components and typically

consume 30μA supply current. Hysteresis is pin selectable at

2°C and 10°C. The temperature switch is specified to operate

over the supply range of 2.7 V to 5.5 V.

3. Supply voltage is 2.7 V to 5.5 V.

4. Supply current of 30 μA.

5. Space-saving 5-lead SOT23 package.

6. Pin selectable temperature hysteresis of 2°C or 10°C.

7. Temperature resolution of 0.0625°C.

ADT6501 and ADT6502 are used for monitoring temperatures

from +35°C to +115°C only. Hence, the logic output pin
