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.
