General Description
The MAX1874 evaluation kit (EV kit) is designed to evaluate the MAX1874 USB and/or AC-adapter-powered, single-cell Li+ battery charger. The EV kit board contains an AC-adapter power jack, a male USB type-B connector, and a charging LED indicator.
The MAX1874 EV kit has four jumpers (JU1–JU4) to easily change the battery charger’s configuration. Jumper JU1 enables or disables charging, jumper JU2 selects the USB charging current for either a maximum of 100mA or 500mA, jumper JU3 allows thermistor sensing, and jumper JU4 sets the DC input fast-charge current for either 750mA or 1A. The DC input fast charge current is also resistor-adjustable.
The DC input accepts up to 18V, but inhibits charging above 6.2V. The USB input accepts inputs up to 6.5V.
