Product Details

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.
