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-drain. The ADT6402 logic output is active
high and push-pull. The temperature is digitized to a resolution
of 0.125癈 (11-bit). The pin-selectable trip point settings are
10癈 apart starting from 45癈 to +5癈 for undertemperature
switching, and from 45癈 to 115癈 for overtemperature
switching.
These devices typically consume 30 糀 of supply current. Hystere-
sis is pin selectable at 2癈 and 10癈. 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癈 to 115癈, 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癈 to +5癈, the logic output pin becomes active
when the temperature goes lower than the selected trip point
temperature.
