Question
VOPRG pin of L6924D
When status of VOPRG pin is sampled by L6924D battery charger IC ? Is this sampled only from rising edge of VIN, all the time or from some other event)?
Would it be ok to control VOPRG with collector of external NPN transistor (emitter of that transistor would be connected directly to GND)?
Aim here would be to start charging with 4.1V and then switch target charging voltage freely (between values 4.1V or 4.2V) when control system is up and running.
