temperature. When any of the monitored parameters is
over the threshold, the IC turns off the charging current.
All protections also have deglitch time against false triggering due to voltage spikes or current transients.
The APL3218 integrates a 5.5V LDO to prevent ACIN overshoot reaching CHR_LDO and OUT. When any transient
peak voltage above 5.5V presenting in ACIN pin, but below 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 current from the GATDRV pin, the OUT pin delivers the charging current which is 200-fold magnified in amplitude
based on GATDRV’s current.
(RoHS Compliant)
Other features include accurate VVCDT/VACIN Voltage divider,
reverse current blocking from OUT to ACIN and OTP

Function Description
Temperature Protection
When the junction temperature exceeds 160oC, the internal thermal sense circuit turns off the power FET and
allows the device to cool down. When the device?¦s junction temperature cools by 40 oC, the internal thermal
sense circuit will enable the device, resulting in a pulsed
output during continuous thermal protection. Thermal
protection is designed to protect the IC in the event of
over temperature conditions. For normal operation, the
junction temperature cannot exceed TJ=+125oC.
