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 (active-low EN1 and active-low EN2) 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.
The MAX8606 EV kit can also be used to evaluate the MAX8856. To evaluate the MAX8856, request a free sample along with the EV kit.
