FEATURES  
DESCRIPTION

•
•
LOW POWER: 5mA (max)  
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).  
SOT563 PACKAGE: 1,6 x 1,6 x 0,6 mm  
TRIP POINT ACCURACY: ±0.2°C from –40°C to  
+125°C  
These devices require no additional components for  
operation; each can function independent of  
microprocessors or microcontrollers.  
•
•
•
PUSH-PULL OUTPUT  
SELECTABLE HYSTERESIS: 1/2/5/10°C  
SUPPLY VOLTAGE RANGE: 1.4V to 3.6V  
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.
