Digital Temperature Sensor with SPI^™Interface

Features

General Description

• Temperature-to-Digital Converter

The TC72 is a digital temperature sensor capable of

reading temperatures from -55°C to +125°C. This sen-

sor features a serial interface that allows communica-

tion with a host controller or other peripherals. The

TC72 interface is compatible with the SPI protocol. The

TC72 does not require any additional external compo-

nents. However, it is recommended that a decoupling

capacitor of 0.01 µF to 0.1 µF be provided between the

•

SPI™ Compatible Interface

• 10-Bit Resolution (0.25°C/Bit)

• ±2°C (max.) Accuracy from -40°C to +85°C

• ±3°C (max.) Accuracy from -55°C to +125°C

• 2.65V to 5.5V Operating Range

• Low Power Consumption:

- 250 µA (typ.) Continuous Temperature

Conversion Mode

- 1 µA (max.) Shutdown Mode

• Power Saving One-Shot Temperature

Measurement

and GND pins.

The TC72 can be used either in a Continuous Temper-

ature Conversion mode or a One-Shot Conversion

mode. The Continuous Conversion mode measures

the temperature approximately every 150 ms and

stores the data in the temperature registers. In con-

trast, the One-Shot mode performs a single tempera-

ture measurement and returns to the power saving

shutdown mode.

The TC72 features high temperature accuracy, ease-

of-use and is the ideal solution for implementing ther-

mal management in a variety of systems. The device is

available in both 8-pin MSOP and 8-pin DFN space-

saving packages. The TC72 also features a shutdown

mode for low power operation.

Typical Applications

• Personal Computers and Servers

• Hard Disk Drives and Other PC Peripherals

• Entertainment Systems

• Office Equipment

• Datacom Equipment

• Mobile Phones

• General Purpose Temperature Monitoring
