Product Details

The MAX8804Z evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the highly integrated MAX8804Z linear battery charger for single-cell lithium-ion (Li+) batteries. The EV kit safely charges a single Li+ battery to 4.2V. The EV kit accepts a 4.15V to 30V DC source voltage or a 4.15V to 16V USB input voltage, but disables charging when either input voltage exceeds 7.5V to protect against unqualified or faulty input sources. A simple single-wire SET input to the EV kit allows the user to enable/disable the charger or program the charge current and top-off threshold. Three LEDs on the EV kit indicate the power-OK, USB power status, and charger status. The MAX8804Z EV kit can also evaluate the MAX8804V/MAX8804W/MAX8804Y. To evaluate the MAX8804V/MAX8804W/MAX8804Y, order a free sample along with this EV kit.
