The MAX8971 evaluation kit (EV kit) demonstrates the MAX8971 IC, a 1.55A capable, 1-cell lithium-ion (Li+) DC-DC battery charger with I2C capability. The EV kit charges a single-cell Li+ battery from a DC input (AC adapter) or a USB 100mA/500mA source and provides system power from the DC input, USB input, or battery. Battery-charge current and input-current limits are independently set. Charge current and input-current limit can be set up to 1500mA. USB suspend mode is also supported.
The EV kit comes standard with the MAX8971EWP+ installed. The included MINIQUSB interface board can be used to enable PC communication through the USB interface board. Windows® 2000-, Windows XP®-, Windows Vista®-, and Windows 7-compatible software along with an extender board allows an IBM-compatible PC with an available USB port to emulate an I2C 2-wire interface. This program is menu-driven and offers a graphical user interface (GUI) with control buttons.
