The CXPR7164 provides complete Li+ charger protection against input over-voltage, input over-current and overtemperature. 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 CXPR7164 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. Other features include accurate VVCDT/VACIN voltage divider, reverse current blocking from OUT to ACIN and OTP protection. The CXPR7164 provides complete Li+ charger protections, and saves the external MOSFET and Schottky diode for the charger of cell phone’s PMIC. The above features and small package make the CXPR7164 an ideal Pin Configuration part for cell phones applications
