Data Sheet Low Cost, 2.7 V to 5.5 V, Pin-Selectable Temperature Switches in SOT-23 ADT6401/ADT6402 07415-001 FEATURES ±0.5°C (typical) threshold accuracy Pin-selectable trip points from −45°C to +5°C in 10°C increments (undertemperature) 45°C to 115°C in 10°C increments (overtemperature) Maximum operating temperature of 125°C Open-drain output (ADT6401) Push-pull output (ADT6402) Pin-selectable hysteresis of 2°C and 10°C Supply current of 30 µA (typical) Space-saving, 6-lead SOT-23 package APPLICATIONS 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 available in a 6-lead SOT-23 package. Each part 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 ADT6401 logic output is active low and open-...
