Description

The TMP303A is a temperature range monitor that offers design flexibility through its extra small footprint (SOT563), low power (5µA max) and low supply voltage capability (as low as 1.4V).

This device requires no additional components for operation; it 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, 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.
