DESCRIPTION
The TMP303A and TMP303B are temperature range
monitors that offer design flexibility through an extra
small footprint (SOT563), low power (5mA 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. When the SOH pin is forced high, the OUT
pin goes high regardless of the measured
temperature.
