− | And here is the schematic. This schematic is basically taken straight from the datasheet, with the exception of the Status LEDs. The Status pin is tristate when not charging, Low when charging, and High when fully charged. This circuit shows both leds on when no battery is present, Red (LED1) when charging and Green (LED2) when fully charged. The 2.2KOhm resistor sets how fast the charger charges. A value of 2.2KOhm will give just under 500mA charge. Higher value means slower charge. | + | And here is the schematic.
