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.
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 3 LSBs of the I
They can be set to V
V
This is the supply voltage pin, and ranges from +2.7 V to +5.5 V.
