GENERAL DESCRIPTION
The ADT6501/ADT6502/ADT6503/ADT6504 are trip point
temperature switches available in a 5-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 ADT6501/
ADT6503 logic output is active low and open-drain. The
ADT6502/ADT6504 logic output is active high and push-pull.
The temperature is digitized to a resolution of 0.125°C (11-bit).
The factory trip point settings are 10°C apart starting from
45°C to +15°C for the cold threshold models and from +35°C
to +115°C for the hot threshold models.
These devices require no external components and typically
consume 30 μA 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.
The ADT6501 and ADT6502 are used for monitoring
temperatures from +35°C to +115°C only. Therefore, the logic
output pin becomes active when the temperature goes higher
than the selected trip point temperature.
The ADT6503 and ADT6504 are used for monitoring tempera-
tures from 45°C to +15°C only. Therefore, the logic output
pin becomes active when the temperature goes lower than the
selected trip point temperature.
