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 0.1 µF bypass capacitor on V
recommended. The sensing device of STCN75 is the chip itself. The typical interface
connection for this type of digital sensor is shown in

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.
