SBOS486B –JULY 2009–REVISED JANUARY 2011

Easy-to-Use, Low-Power, 1°C, Low-Supply

TEMPERATURE RANGE MONITOR in MicroPackage

Check for Samples: TMP303A, TMP303B

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.

APPLICATIONS

•

CELL PHONE HANDSETS

PORTABLE MEDIA PLAYERS

CONSUMER ELECTRONICS

SERVERS

POWER-SUPPLY SYSTEMS

DC-DC MODULES

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.
