In order to protect downstream devices on the system rail, the input over-voltage threshold can be programed with the ACOV pin as VVACOV = VREF_ACOV (refer to Section 7.3.3.1). The device also features an internal over-voltage protection preset at VVAC_INT_OV. When the input voltage rises above the lower of these two thresholds, the device disables the controller. During input over-voltage, an INT pulse is asserted to signal the host, and the VAC_OV_STAT, and _FLAG bits are set. Additionally, the PG_STAT bit is cleared and the PG pin pulls HIGH. The device automatically resumes operation when the over-voltage condition goes away.
