Specifications of MAX44000EVKIT+

• Tool Is For Evaluation Of: MAX44000
• Interface Type: I2C
• Description/function: Sensor Kit
• Operating Supply Voltage: 3.6 V

The MAX44000 EV system includes one MAX44000 EV kit
and one MAX44000 daughter board. The EV kit is a fully
assembled and tested PCB that evaluates the device
ambient light and proximity sensor. The EV kit comes
installed with a MAX44000GDT+ in a 6-pin OTDFN pack-
age with an exposed pad.
The daughter board is an external device-under-test mod-
ule that also comes with a MAX44000GDT+ installed. The
daughter board can be connected to and controlled by
the EV kit. The user can also evaluate the device by con-
necting the user-supplied controller to the daughter board.
The on-board IR LED is installed next to the device. A
light dam board is placed between the IR LED and the
device to block crosstalk.
To use a user-supplied IR LED, install the user-supplied
IR LED on the IRLED2 footprint and place a shunt on
jumper JU17 in the 1-4 position.
To use an external IR LED, connect the external IR LED
between the EXIRLED1 and EXIRLED2 connectors. Then
place the shunt on JU17 in the 1-3 position.

The on-board LDO (U6) provides a 3.6V output to the EV kit.
Disconnects the output of the on-board LDO (U6).
The on-board LDO (U7) provides a 2.5V output to the EV kit.
Disconnects the output of the on-board LDO (U7).
The on-board LDO (U10) provides a 1.2V output to the EV system.
Disconnects the output of the on-board LDO (U10).
On-board LDOs powered from the USB port.
Connect an external 5V supply to the DVDD connector.
The on-board LDO (U15) provides a 1.8V output to the EV system.
Disconnects the output of the on-board LDO (U15).
The on-board 2.5V supply connects to the anode of the IR LED.
Connect an external supply to the VLED connector.
The on-board 1.8V supply connects to the VDD pin of the device.
Connect an external supply to the EXT_VDD connector.
SDA signal on the device connected to the on-board microcontroller.
Connect user-supplied SDA signal to the on-board EXT_SDA pad.
SCL signal on the device connected to the on-board microcontroller.
Connect user-supplied SCL signal to the on-board EXT_SCL pad.
INT signal on the device connected to the on-board microcontroller.
Connect user-supplied INT signal to the on-board EXT_INTB pad.
DRV signal on the device connected to the cathode of the IRLED1.
DRV signal on the device connected to the EXIRLED2 connector.

By default, the EV kit is USB powered. To use an external
power supply, connect a 5V supply to the DVDD and
DGND connectors, and place a shunt on jumper JU10
in the 2-3 position. The daughter board is powered by its
master board.
To use the device on the EV kit with a user-supplied I
interface, install shunts on jumpers JU12–JU16 in the 2-3
position. Connect the SCL, SDA, INT, VDD, and VLED
signals from the external I
EXT_SDA, EXT_INTB, EXT_VDD, and VLED connectors
on the EV kit, respectively.
To use the daughter board with the EV kit and the EV
kit software, remove the shunts on jumpers JU14, JU15,
and JU16 to disconnect the device on the EV kit from
the on-board controller. Carefully connect the EV kit and
the daughter board by aligning the 6-pin right-angle
connector (J1) on the daughter board with the 6-pin right-
angle header (J4) on the EV kit, and press them together.
