The MAX8725 evaluation kit (EV kit) is an accurate and
efficient multichemistry battery charger. The EV kit can
charge three or four series Li+ cells with a current up to
3A. Charge current and input-source current are
adjustable using on-board potentiometers. The output
voltage is set to 4.2V • the number of series cells in the
battery pack. The number of series cells is jumper selectable.
The output voltage is adjustable between 4V to
4.4V (x the number of series cells) by installing two resistors.
The EV kit provides outputs to monitor the AC-adapter
current and the presence of an AC adapter.
The MAX8725 automatically selects the power path for
supplying power to the system by controlling two external
p-channel MOSFETs. This decision is made based on the
presence of an AC adapter.
