6 SCHEMATICS

Above is a schematic on EV3419A. This is the factory preset when receiving the part.

For other options, please refer to the following table:

Interface

R1

R2

R3

SPI or I2C 0x4C (

Factory default

)

100KΩ

DNI

1

10KΩ

SPI or I2C 0x6C

100KΩ

10KΩ

DNI

R4, R5:

Install ~4.7K

Ω as the I2C pull-ups if using I2C mode and there is no I2C pull-ups

installed. (DNI by default)

Note: It is recommended not to install more than one pull-ups per I2C bus.

R6:

Install ~4.7K

Ω

pull-up resistor if setting the sensor interrupt pin to open-drain. (DNI by default)

R7:

Sensor’s driving current can be measured by putting an ammeter in place of R7.

The physical location of the resistor is in the diagram in Section 8.
