MAX44009 Evaluation Kit

Evaluates: MAX44009

General Description

The MAX44009 evaluation kit (EV kit) is a fully assembled

and tested surface-mount PCB that evaluates the

MAX44009 low-power ambient light sensor. The EV kit

can be powered directly from the universal serial bus

(USB) or from a single-supply voltage of 1.7V to 3.6V.

The EV kit provides an on-board I

C/SMBus interface

and is connected to the computer through the USB port.

The EV kit includes Windows XP

-, Windows Vista

and Windows

7-compatible software that provides

a simple user interface for exercising the device’s

features. The program is menu driven and offers a

graphical user interface (GUI) complete with control

buttons and status displays.

The on-board device can also be controlled by an

external master, allowing users to test different code

implementations to interface with the part.

MAX44009 Interface Diagnostic Window Detailed Description of Hardware I2C Bus Lines The MAX44009 EV kit features an on-board I2C/SMBus interface control through the USB. To use the EV kit with a user-supplied I2C/SMBus interface, move the shunts on jumpers JU1 and JU2 to the 2-3 position. Then connect the SDA and SCL signals to the corresponding SDA and SCL PCB pads on the EV kit board. Table 1 lists the selectable jumper options.
