| MCP73864 Li-Ion charger I have bought an 8.2v 2200mah Li-Ion
battery in Ritchie Street Chennai. My first problem was
charging the battery. A quick check in farnell india
through Kits ‘n’ spare provided me the option
MCP73864.
The beauty is this chip can handle charging current up to
1.2A with auto charging cut-off.
I have done a quick check with readymade SOIC PCB (Got it
from Sundaram PCBs, Raheja complex,Ritche street
Chennai).
Result is perfect. I am yet to determine the charging
duration for a completely dry battery. Will update. For
now please find herewith the Circuit, PCB in Eagle and
PDF format.
 
Caution : Li-Ion batteries are dangerous and may explode
if mishandled over riding its spec. Please take most
care.
