The MAX8606 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board demonstrating
the MAX8606 linear charger for single-cell Li+ batteries.
The EV kit operates from either a 100mA/500mA USB
port or a 4.25V to 14V input power supply; however,
charging is disabled when the input voltage exceeds
5.8V. Charging is optimized for Li+ cells using a control
algorithm that includes low-battery precharging, voltage
and current-limited fast-charging, and top-off
charging, while continuously monitoring the battery for
overvoltage, over/under temperature, and charging
time. A 3.5V to 4.2V SYS output, in conjunction with the
low-RDSON battery switch, powers the system even
when the battery is deeply discharged or not installed.
The charger status is indicated by two open-drain outputs.
Two logic inputs (EN1-bar and EN2-bar) select suspend
mode, 100mA, 500mA, or 750mA fast-charge mode.
The maximum charge current is programmable up to
1A. The MAX8606 is assembled in the space-saving
14-pin, 3mm x 3mm TDFN package.
