C Bus Lines
The MAX44009 EV kit features an on-board I

C/SMBus
interface control through the USB. To use the EV kit with
a user-supplied I
2
C/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.
Hardware Interrupt
The EV kit features an on-board hardware-interrupt
control. To use the EV kit with a user-supplied interrupt
interface, move the shunt on jumper JU3 to the 2-3
position. Then, connect the INT signal to the INT PCB
pad on the EV kit board. Table 2 lists the selectable
jumper options.
Power Input
The device can operate from a single-supply VCC
between 1.7V and 3.6V. Using the 3-pin jumper JU4,
the device can be powered either by the on-board 1.8V
power supply (default shunt position across pins 1-2)
or by an external power supply (shunt across pins 2-3).
Table 3 lists the selectable jumper options.
