Hi
Is it possible to have some type of isolation circuit to isolate the battery from the circuit that is powering when the battery is charging, when the voltage drops less then 3V?
There was an incident when the battery voltage drop to about 2.5V, the Li-Ion charger IC provides about 10mA of charge to recondition the battery, but after a while the microcontroller or remaining part of the circuit power ups and uses the little provided charge in the battery. This cause the battery not progress past the deep charging cycle. This continued till I had remove the battery and use a standalone charger.
Is it possible that we can place a MOSFET or switch between battery and remaining circuit, so that when the battery voltage reaches 3.5V it then powers the reaming system?
I have tried a simple toggle switch, but notice some unusual performance issues on my RF circuit. I presume the switch must have added some resistance or interference.
I am looking if there is a better option, so that the MOSFET or discrete switch can help recover a battery during charging?
