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
2
C) standards. The
default SMBus/I
2
C address of the NVT210 is 0x4C. An NVT210D is
available with an SMBus/I
2
C address of 0x4D. This is useful if more
than one NVT210 is used on the same SMBus/I
2
C.
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.
