3 Description
The TMP75C-Q1 is an integrated digital temperature
sensor with a 12-bit analog-to-digital converter (ADC)
that can operate at a 1.8-V supply, and is pin and
register compatible with the NCT75 and ADT75. This
device is available in SOIC-8 and VSSOP-8
packages and requires no external components to
sense the temperature. The TMP75C-Q1 is capable
of reading temperatures with a resolution of 0.0625°C
and is specified over a temperature range of –40°C to
+125°C.
The TMP75C-Q1 features SMBus and two-wire
interface compatibility, and allows up to eight devices
on the same bus with the SMBus overtemperature
alert function. The programmable temperature limits
and the ALERT pin allow the sensor to operate as a
stand-alone thermostat, or an overtemperature alarm
for power throttling or system shutdown.
The factory-calibrated temperature accuracy and the
noise-immune digital interface make the TMP75C-Q1
the preferred solution for temperature compensation
of other sensors and electronic components, without
the need for additional system-level calibration or
elaborate board layout for distributed temperature
sensing.
The TMP75C-Q1 is ideal for thermal management
and protection of a variety of consumer, computer,
communication, industrial, and environmental
applications.
