The TMP303A and TMP303B are temperature range monitors that offer design flexibility through an extra small footprint (SOT563), low power (5µA max) and low supply voltage capability (as low as 1.4V).
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 of 0°C to +60°C (TMP303A), 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
