NVT211/D

NVT211

+15C Temperature Monitor

with Series Resistance

Cancellation

The NVT211 is a dual-channel digital thermometer and

undertemperature/overtemperature alarm, intended for use in thermal

management systems. It is register-compatible with the NCT1008 and

NCT72. A feature of the NVT211 is series resistance cancellation,

where up to 1.5 k

W (typical) of resistance in series with the temperature

monitoring diode can be automatically cancelled from the temperature

result, allowing noise filtering. The NVT211 has a configurable ALERT

output and an extended, switchable temperature measurement range.

The NVT211 can measure the temperature of a remote thermal diode

accurate to

±1°C and the ambient temperature accurate to ±3°C. The

temperature measurement range defaults to 0

°C to +127°C, compatible

with the NCT1008 and NCT72, but it can be switched to a wider

measurement range of −64

°C to +191°C.

The NVT211 communicates over a 2-wire serial interface,

An ALERT output signals when the on-chip or remote temperature is

out of range. The THERM output is a comparator output that allows

on/off control of a cooling fan. The ALERT output can be reconfigured

as a second THERM output, if required.

The NVT211 has been through Automotive Qualification according to

AEC−Q100 Grade 1 standards.
