TMP75B 1.8-V Digital Temperature Sensor with Two-Wire Interface and Alert

1 Features

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

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.

•

Low-Voltage Alternative to LM75 and TMP75

•

Digital Output with Standard Two-Wire Serial

Interface

•

Up to 8 Pin-Programmable Bus Addresses

Overtemperature ALERT Pin with Programmable

Trip Values

•

Shutdown Mode for Battery Power Saving

One-Shot Conversion Mode for Custom Update

Rates

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.

•

Operating Temperature Range: –55°C to +125°C

Operating Supply Range: 1.4 V to 3.6 V

Quiescent Current:

–

45 μA Active (typ)

0.3 μA Shutdown (typ)

•

Accuracy:

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.

–

±0.5°C (typ) from –20°C to +85°C

±1°C (typ) from –55°C to +125°C

•

Resolution: 12 Bits (0.0625°C)

Packages: SOIC-8 and VSSOP-8
