Pin descriptions
See
Figure 1 on page 7
and
Table 1 on page 7
for a brief overview of the signals connected
to this device.
1.3.1
SDA (open drain)
This is the Serial Data Input/Output pin for the 2-wire serial communication port.
1.3.2
SCL
This is the Serial Clock Input pin for the 2-wire serial communication port.
1.3.3
OS/INT (open drain)
This is the Over-Limit 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
OS
). It behaves as a thermostat, toggling to indicate whether
the measured temperature is above or below the threshold and hysteresis (T
HYS
).
