General Description
over the threshold, the IC turns off the charging current.
All protections also have deglitch time against false trig-
gering due to voltage spikes or current transients.
The APL3225 integrates a 5.5V LDO to prevent ACIN over-
shoot reaching CHR_LDO and OUT. When any transient
peak voltage above 5.5V presenting in ACIN pin, but be-
low OVP threshold, the internal LDO will clamp its output
at 5.5V. When ACIN voltage exceeds OVP threshold, the
device will turn off charging current. The charging current
is controlled by the GATDRV pin. When sourcing a cur-
rent from the GATDRV pin, the OUT pin delivers the charg-
ing current which is 200-fold magnified in amplitude
based on GATDRV’s current.
Other features include accurate VVCDT/VACIN voltage divider,
