DESCRIPTION
JU2
1-2
Connects the IC charger output to the MEC (BATT) directly. To prevent possible IC damage,
JU2 must always be the first jumper installed and the last jumper removed.
2-3
Connects the IC charger output to the MEC (BATT) through a 10I resistor (R6). Use this setting
to measure the charger current. To prevent possible IC damage, JU2 must always be the
first jumper installed and the last jumper removed.
Not installed* The IC is not connected to the battery.
JU3
Installed The on-board solar cells power the EV kit.
Not installed*
For low-voltage DC external energy-harvesting sources, remove this shunt and apply the power
source to the SOLAR+ test point.
JU4 Not installed* See the Regulator Output Voltage (SEL1) section.
JU5
Installed Connects LED D5 to the battery pack output (PCKP test point).
Not installed*
Disconnects LED D5 from the PCKP test point. The PCKP output can be used to power an
external load.
JU6
Installed Enables the LED indicator.
Not installed* Disables the LED indicator.
JU7
Installed Connects the resistor-divider to FB.
Not installed* Does not connect the resistor-divider to FB.

MAX17710GB20 Evaluation Kit
Evaluates: MAX17710GB
Detailed Description of Hardware
The MAX17710GB20 EV kit is a fully assembled and
tested PCB that contains all the components neces sary
to evaluate the MAX17710GB energy-harvesting charger
and protector. The IC is available in a 12-pin UTDFN
package with an exposed pad. The EV kit circuit uses
a boost controller to regulate and charge the on-board
THINERGY MEC201 (BATT). The EV kit has three on-
board solar cells that are connected in parallel. On-board
jumpers and test points allow external power sources to
power the IC. The IC has low reverse leakage to prevent
discharge of the on-board energy cell. Ambient light can
charge the on-board MEC with current as low as 1FA
