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.
