Can i charge a 7.2v Li-ion cell from a 7.5v 1200mA supply?
This supply also runs a GPRS application drawing 300mA with 1A pulses.
What i would like is a circuit that trickle charges the Li-ion cell (dont care how long it takes) but also runs the application, then on mains failure the battery needs to take over.
Will a FET so the neccessary switching between battery power & apadter power ?
