The TMP303CDRLR devices are temperature range monitors that offer design flexibility throughan extra small footprint (SOT-563), low power (5 μA maximum) and low supply voltage capability (aslow as 1.4 V).
These devices require no additional components for operation; each can functionindependent of microprocessors or microcontrollers.
There are seventrip points available see Device Options.Trip points can be programmed at the factory to any desired temperature. For applications thatrequire different values, contact your local TI representative.
The OUT pin is a push-pull, active-high output. When the measured temperature is beyondthe trip point range, and the Set Output High (SOH) pin is low, the OUT pin is high. The SOH pin isan input pin with an internal pulldown resistor. When the SOH pin is forced high, the OUT pin goeshigh regardless of the measured temperature.
