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.

Note:

The open drain thermostat output that indicates if the temperature has exceeded user-

programmable limits (Over/Under Temperature indicator).

1.3.4

GND

Ground; it is the reference for the power supply. It must be connected to system ground.

1.3.5

A2, A1, A0

A2, A1, and A0 are selectable address pins for the 3LSBs of the I2C interface address. They

can be set to VDD or GND to provide 8 unique address selections.

1.3.6

VDD

This is the supply voltage pin, and ranges from +2.7V to +5.5V.
