up—in this case, it is possible to achieve a thermal
response in as little as 35ms.
CONFIGURING THE TMP302
The TMP302 is simple to configure. The only external
components that it requires are a bypass capacitor
and pull-up resistor. Power-supply bypassing is
strongly recommended; use a 0.1F capacitor placed
as close as possible to the supply pin. To minimize
the internal power dissipation of the TMP302, use a
pull-up resistor value greater than 10k
Ω from OUT to
VS. Refer to Table 1 for trip point temperature
configuration. The TRIPSET pins can be toggled
dynamically; however, the voltage of these pins must
not exceed VS. To ensure a proper logic high, the
voltage must not drop below 0.7V × VS.
