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 0.1µF 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
