DESCRIPTION

NAME

V_DD

NO.

Supply Voltage. From 1.62 V to 5.50 V.

Ground

GND

SCL

Serial clock line for I²C, open-drain; requires a pullup resistor to V_DD

SDA

I/O

Serial data line for I²C, open-drain; requires a pullup resistor to V_DD

I²C Device Address Pin.

For device addresses 0x44 and 0x45, ADDR1 voltage must be below maximum V_ILor left floating.

0x44 requires ADDR voltage to be below maximum V_ILor left floating.

0x45 requires ADDR voltage to be above minimum V_IH.

ADDR

I²C Device Address Pin.

For device addresses 0x46 and 0x47, ADDR1 voltage must be above minimum V_IH.

0x46 requires ADDR voltage to be below maximum V_ILor left floating.

0x47 requires ADDR voltage to be above minimum V_IH.

ADDR1

RESET

ALERT

Reset Pin. Active Low. If not used, leave floating or tie to V_DD.

Interrupt Pin to drive high impedance loads. Push-Pull Output.

If not used, must be left floating.
