Operation description
L6924D
12/38
When the VPRE pin is not used to program the Pre-Charge voltage threshold, it has two
different functions:
●
If the voltage across VPRE pin is lower than 0.8V, when I < IENDTH, the end of charge in
notified by the status pin, but the charging process is not disabled. The charge process
ends when the maximum charging time expires.
●
If pin VPRE goes lower than 0.5V the timer is reset on the falling edge.
Battery disconnection control is provided thanks to the differentiated sensing and forcing output
pins. A small current is sunk and forced through VOUT. If VOSNS doesn’t detect the battery, the
IC goes into a standby mode.
