Applications information
STDS75 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 is recommended.
The sensing device of STDS75 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
