3 Description

The TMP75B 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 industry-standard LM75

and TMP75. This device is available in SOIC-8 and

VSSOP-8 packages, and requires no external

components to sense the temperature. The TMP75B

is capable of reading temperatures with a resolution

of 0.0625°C and is specified over a temperature

range of –55°C to +125°C.

The TMP75B 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 TMP75B 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 TMP75B is ideal for thermal management and

protection of a variety of consumer, computer,

communication, industrial, and environmental

applications.
