3 Description
The TMP303 devices are temperature range monitors
that offer design flexibility through an extra small
footprint (SOT-563), low power (5 μA maximum) and
low supply voltage capability (as low as 1.4 V).
These devices require no additional components for
operation; each can function independent of
microprocessors or microcontrollers.
There are seven trip points available see Device
Options. Trip points can be programmed at the
factory to any desired temperature. For applications
that require different values, contact your local TI
representative.
The OUT pin is a push-pull, active-high output. When
the measured temperature is beyond the trip point
range, and the Set Output High (SOH) pin is low, the
OUT pin is high. The SOH pin is an input pin with an
internal pulldown resistor. When the SOH pin is
forced high, the OUT pin goes high regardless of the
measured temperature.
