The MAX8601 evaluation kit (EV kit) is a fully assembled
and tested surface-mount PC board demonstrating the
MAX8601 single-cell, linear Li+ battery charger. The EV
kit operates from either a 100mA/500mA USB port or a
4.15V to 14V input power supply; however, charging is
disabled when the input voltage exceeds 7V. 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.
The charger timeout protection is programmable. The
charger status is indicated by three open-drain outputs.
The MAX8601 automatically selects between either a
USB or an AC-adapter input source. The AC-adapter
charge current is programmable, while the USB charge
current is preset not to exceed either 100mA or 500mA,
depending on the USEL input. The MAX8601 EV kit also
evaluates the MAX8600 with no PC board modification.
The MAX8601 is assembled in the space-saving 3mm x
3mm, 14-pin TDFN package.
