NVT210/D

NVT210

+15C Temperature Monitor

with Series Resistance

Cancellation

The NVT210 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 NVT210 is series resistance cancellation,

where up to 1.5 kW (typical) of resistance in series with the temperature

monitoring diode can be automatically cancelled from the temperature

result, allowing noise filtering. The NVT210 has a configurable ALERT

output and an extended, switchable temperature measurement range.

The NVT210 can measure the temperature of a remote thermal diode

accurate to ?癈 and the ambient temperature accurate to ?癈. The

temperature measurement range defaults to 0癈 to +127癈, compatible

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

measurement range of 64癈 to +191癈.

The NVT210 communicates over a 2-wire serial interface,

compatible with system management bus (SMBus/I

C) standards. The

default SMBus/I

C address of the NVT210 is 0x4C. An NVT210D is

available with an SMBus/I

C address of 0x4D. This is useful if more

than one NVT210 is used on the same SMBus/I

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 NVT210 has been through Automotive Qualification according to

AECQ100 Grade 1 standards.
