Product Details

The MAX8677A evaluation kit (EV kit) demonstrates the MAX8677A dual-input charger and Smart Power Selector™ IC. The EV kit charges a single-cell Li-ion (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. The DC input has a resistor-adjustable current limit, while USB current input limit is logic programmed to 100mA/500mA. USB suspend mode is also supported. The charge current is adjustable from 300mA to 1.5A. The system load has priority over the charger so that charge current is reduced as necessary to prevent input overload. Charge current is also thermally regulated.
