Hi there,

I working on a project that will use a MCP73113 http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en541458 battery charger a 3.7V lipo battery. It is similar to the Sparkfun lipo charger except that this can charge at 1000mA.

I plan on using a digital pin of the Arduino Mega2560 to determine whether the battery is charging or is complete. Please see my attached drawing. 'STAT' has low impedance when the battery is charger and high impedance when charging is complete.

I would like to be able to read the state (HIGH or LOW) using the Mega at the position shown to determine whether the battery is charging or is complete (the light is on or off).

Is the pin position correct with this circuit?

Cheers
