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.
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 Over-Limit Signal/Interrupt Alert Output pin. It is open drain, so it needs a pull-up
resistor.
The open drain thermostat output that indicates if the temperature has exceeded user-
programmable limits (Over/Under Temperature indicator).
GND
Ground; it is the reference for the power supply. It must be connected to system ground.
A2, A1, A0
A2, A1, and A0 are selectable address pins for the 3LSBs of the I²C interface address. They
can be set to V_DD or GND to provide 8 unique address selections.
V_DD
This is the supply voltage pin, and ranges from +2.7V to +5.5V.
