Applications information

STLM75 digital temperature sensors are optimal for thermal management and thermal

protection applications. They require no external components for operations except for pull-

up resistors on SCL, SDA, and OS/INT outputs. A 0.1 µF bypass capacitor on VDD is

recommended. The sensing device of STLM75 is the chip itself. The typical interface

connection for this type of digital sensor is shown in Figure 4 on page 11.

Intended applications include:

●

System thermal management

●

Computers/disk drivers

●

Electronics/test equipment

●

Power supply modules

●

Consumer products

●

Battery management

●

Fax/printers management

●

Automotive
