Programmable Battery Charger Ic

The top up charge is typically initiated when the open circuit voltage of the battery drops to less than 3 9 to 4 v and terminates when the full charge voltage of 4 1 to 4 2 v is again attained.

Programmable battery charger ic.

If the charger is left connected to the battery a periodic top up charge is applied to counteract battery self discharge. Using a programmable charger allows the designer to use the same battery charging circuit and only modify the charge parameters in order to charge a lifepo 4 battery.
