PRODUCTION DATA
The charger device clamps the system voltage during a load transient so that the components connected to the system are not damaged due to high voltage. The VSYS_OVP threshold is about 300 mV above battery regulation voltage when battery charging is terminated. Upon SYSOVP, the converter stops switching immediately to clamp the overshoot. The charger pulls 30-mA ISYS_LOAD discharge current to bring down the system voltage.
