If VBUS voltage exceeds VVAC_OV (programmable via OVP[2:0] bits), the device stops switching immediately.
During input overvoltage event (ACOV), the fault register CHRG_FAULT bits are set to 01. An INT pulse is asserted to the host. The device will automatically resume normal operation once the input voltage drops back below the OVP threshold.
