NCT203

Low Voltage, High

Accuracy Temperature

Monitor with I²C Interface

The NCT203 is a digital thermometer and undertemperature/

overtemperature alarm, intended for use in thermal management

systems requiring low power and size. The NCT203 operates over a

supply range of 1.4 V to 2.75 V making it possible to use it in a wide

range of applications including low power devices.

The NCT203 can measure the ambient temperature accurate to

1.75°C. The device operates over a wide temperature range of −40 to

+125°C.

MT SUFFIX

CASE 511BU

The NCT203 has a configurable ALERT output and over−

temperature shutdown THERM pin.

Communication with the NCT203 is accomplished via the I C

interface which is compatible with industry standard protocols.

Through this interface the NCT203s internal registers may be

accessed. These registers allow the user to read the current

temperature, change the configuration settings and adjust limits.

An ALERT output signals when the on−chip temperature is out of

range. The THERM output is a comparator output that can be used to

shut down the system if it exceeds the programmed limit. The ALERT

output can be reconfigured as a second THERM output, if required.
