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 0.1 µF bypass capacitor on V
recommended. The sensing device of STLM75 is the chip itself. The typical interface
connection for this type of digital sensor is shown in
