Hey

I'm working on a wireless battery charger design. So far, i have inductive coupling to power up a PLL based battery charging circuit.
each circuit works fine in isolation. but when together and when the whole circuit is off, the battery back powers the rest of the circuit rendering it ON even when its supposed to be off.
I want to know if anyone can help me isolate the battery from the Vcc which comes from the inductive coupling side.
I just need to know how to avoid back powering

Thanks
