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.
Trip points are preprogrammed at the factory. 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.
