Operation
2.1
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 0.1 µF 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:
â System thermal management
â Computers/disk drivers
â Electronics/test equipment
â Power supply modules
â Consumer products
â Battery management
â Fax/printers management
â Automotive
