connected to this device.
SDA (open drain)
This is the serial data input/output pin for the 2-wire serial communication port.
SCL
This is the serial clock input pin for the 2-wire serial communication port.
OS/INT (open drain)
This is the overlimit signal/interrupt alert output pin. It is open drain, so it needs a pull-up
resistor. In Interrupt mode, it outputs a pulse whenever the measured temperature exceeds
the programmed threshold (T
the measured temperature is above or below the threshold and hysteresis (T
