The STBC03 uses a CC/CV algorithm to charge the battery; the fast charge and the pre-charge current can be both independently programmed using dedicated resistors.
The termination current is set to 5% of the programmed fast charge current, but has fixed values for fast charge currents lower than 20 mA.
The battery floating voltage value is programmable and can be set to a value up to 4.
45 V.
The STBC03 also features a charger enable input to stop the charging process anytime.
The STBC03 is automatically powered off from the connected battery when the IN pin is not connected t...
