2.1
Applications information
STCN75 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 V
DD
is
recommended. The sensing device of STCN75 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

SDA and OS/INT are open drain.

Thermal alarm function
The STCN75 thermal alarm function provides user-programmable thermostat capability and
allows the STCN75 to function as a standalone thermostat without using the serial interface.
The OS/INT output is the alarm output. This signal is an open drain output, and at power-up,
this pin is configured with active-low polarity by default.
