Features and Benefits of ADT6401
Product Detailed Description for ADT6401
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-drain. The ADT6402 logic output is active high and push-pull. The temperature is digitized to a resolution of 0.125°C (11-bit). The pin-selectable trip point settings are 10°C apart starting from −45°C to +5°C for undertemperature switching, and from 45°C to 115°C for overtemperature switching.

These devices typically consume 30 μA of 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.

When the ADT6401/ADT6402 are used for monitoring tempera- tures from 45°C to 115°C, the logic output pin becomes active when the temperature goes higher than the selected trip point temperature. When the ADT6401/ADT6402 are used for monitoring tempera- tures from −45°C to +5°C, the logic output pin becomes active when the temperature goes lower than the selected trip point temperature.
