TMP708/709EVM Hardware Overview and Setup
www.ti.com
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 Figure 6.
