I am using a LPC1769 board and I want to support it with the battery supply on Pin J6-3! In the data sheet I read that there shouldn't drain a Current of IBAT if the main power supply works. But I meassure a current of IBat =~21mA and it should be around 530nA...
If I cut the main power supply the current IBAT raises to 44mA, but it should be around 1,1uA! Somebody knows how I can fix it?

Greetings Looney :)
