Part Details:

Low Cost, 2.7 V to 5.5 V, Pin-Selectable Temperature Switches in SOT-23 ADT6401/ADT6402 FEATURES FUNCTIONAL BLOCK DIAGRAM V GND ±0.5°C (typical) threshold accuracy CC 4 5 Pin-selectable trip points from -45°C to +5°C in 10°C increments (undertemperature) - ADT6401 TEMPERATURE-TO- 45°C to 115°C in 10°C increments (overtemperature) DIGITAL CONVERTER COMPARATOR Maximum operating temperature of 125°C 6 TOVER/TUNDER Open-drain output (ADT6401) Push-pull output (ADT6402) S2 1 TRIP POINT AND Pin-selectable hysteresis of 2°C and 10°C S1 2 HYSTERESIS 2ºC/10ºC DECODING Supply current of 30 A (typical) S0 3 1 Space-saving, 6-lead SOT-23 package -00 41507 APPLICATIONS Figure 1. Medical equipment Automotive Cell phones Hard disk drives Personal computers Electronic test equipment Domestic appliances Process control GENERAL DESCRIPTION The ADT6401/ADT6402 are trip point temperature switches When the ADT6401/ADT6402 are used for monitoring tempera- available in a 6-lead SOT-23 package. Each part contains an tures from -45°C to +5°C, the logic output pin becomes active internal band gap temperature sensor for local temperature when the temperature goes lower than the selected trip point sensing. When the temperature crosses the trip point setting, temperature. the logic output is activated. The ADT6401 logic output is PRODUCT HIGHLIGHTS active low and open-drain. The ADT6402 logic output is active high and push-pull. The temperature is digitized to a resolution 1. - based temperature measurement gives high accuracy
