PIN NAME

FUNCTION

Serial-Data Input/Output Line. Open drain. Connect SDA to a pullup resistor. High impedance for supply

1

SDA voltages from 0 to 3.7V.

Serial-Data Clock Input. Open drain. Connect SCL to a pullup resistor. High impedance for supply voltages

2

SCL from 0 to 3.7V.

3

OS Overtemperature Shutdown Output. Open drain. Connect OS to a pullup resistor.

4

GND Ground

5

A2

I2C Slave Address Input. Connect A2 to GND or VDD to set the desired I2C bus address. Do not leave

unconnected (Table 1).

6

A1

I2C Slave Address Input. Connect A1 to GND, VDD, SDA, or SCL to set the desired I2C bus address. Do not

leave unconnected (Table 1). High impedance for supply voltages from 0 to 3.7V.

7

A0

I2C Slave Address Input. Connect A0 to GND, VDD, SDA, or SCL to set the desired I2C bus address. Do not

leave unconnected (Table 1). High impedance for supply voltages from 0 to 3.7V.

8

VDD Positive Supply Voltage Input. Bypass to GND with a 0.1mF bypass capacitor.
