Recharge threshold
When, from an end-of-charge condition, the battery voltage goes below the recharging
threshold (VRCH), the device goes back in charging state. The value of the recharge
threshold is 4.05 V.

Maximum charging time
To avoid the charging of a dead battery for a long time, the L6924U has the possibility to set
a maximum charging time starting from the beginning of the fast-charge phase. This timer
can be set through a capacitor, connected between the TPRG pin and GND. CTPRG is the
external capacitor (in nF) and is given by the following equation:
Equation 10
Note:
The maximum recommended CTPRG value must be less than 50 nF.
