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

• SOT563 PACKAGE: 1,6 x 1,6 x 0,6 mm

small footprint (SOT563), low power (5mA max) and

• TRIP POINT ACCURACY: ±0.2°C from –40°C to

low supply voltage capability (as low as 1.4V).

+125°C

These devices require no additional components for

operation; each can function independent of

• SELECTABLE HYSTERESIS: 1/2/5/10°C

microprocessors or microcontrollers.

• SUPPLY VOLTAGE RANGE: 1.4V to 3.6V

Trip points are preprogrammed at the factory. For

applications that require different values, contact your

TMP303A TMP303B SBOS486B – JULY 2009 – REVISED JANUARY 2011 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure.

TMP303A TMP303B SBOS486B – JULY 2009 – REVISED JANUARY 2011 www.ti.com APPLICATION INFORMATION The TMP303A and TMP303B are temperature switches used in battery-powered applications that require accurate monitoring of a very specific temperature range of 0°C to +60°C (TMP303A) or 0°C to +55°C (TMP303B). This functionality is accomplished through the preset trip window and two hysteresis bits, HYSTSET0 and HYSTSET1.

TMP303A TMP303B www.ti.com SBOS486B – JULY 2009 – REVISED JANUARY 2011 TMP303A/B Power Up and Timing The tolerance of the thermal response time is largely a result of the differences in conversion time, which varies between 20ms and 35ms; likewise, this conversion does not take place after a power cycle until the supply voltage has reached a level of at least 1.4V. This sequence is illustrated in Figure 12.
PAGE 8
TMP303A TMP303B SBOS486B – JULY 2009 – REVISED JANUARY 2011 www.ti.com After the TMP303A/B powers up, all successive thermal response results for the device are achieved in a time frame of 0.985s to 1s. This period is the minimum time frame required for the push-pull output (OUT) to change its state from high to low (or vice-versa) while the device is active. A maximum low output voltage is defined as a voltage level equivalent to (0.2 × VS); likewise, a minimum high output voltage is defined as (0.
