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 0.125C (11-bit). The pin-selectable trip point settings are 10C apart starting from -45C to +5C for undertemperature switching, and from 45C to 115C for overtemperature switching.
