TMP708/709EVM Hardware Overview and Setup
For example, a TMP709 with its trip point set to 100
°
C asserts when its temperature rises above +100
°
C,
and does not de-assert until its temperature drops below +100
°
C minus the selected hysteresis value (that
is, +98
°
C if 2
°
C hysteresis is chosen). Conversely, if the trip temperature of the TMP709b is
–
40
°
C, the
output asserts at
–
40
°
C as temperature falls, and de-asserts when temperature rises above
–
40
°
C plus
the hysteresis value (that is,
–
38
°
C if 2
°
C hysteresis is chosen). This behavior is shown in
