6.3.4.2 Output Overvoltage Protection (VOUT_OVP)

If the voltage at the OUT pin exceeds VOUT_OVP, the device immediately stops charging.The safety timer suspends counting and the device enters Standby mode. Once the OUT voltage recovers to a normal level, the charge cycle and the safety timer automatically resume operation.
