Description
1 = input voltage on VAC is larger than the value in VIN_OV_FAULT_LIMIT (Register 0x55).
1 = an overvoltage condition is present on the VCORE rail.
1 = input overpower warning.
1 = controller is not able to detect the ac line period; the maximum value of the period is used
and this flag is set.
1 = input current measured on the CS ADC is larger than the value in IIN_OC_WARN_LIMIT
(Register 0x5D).
1 = input current measured on the CS ADC is larger than the value in IIN_OC_FAULT_LIMIT
(Register 0x5B).
1 = the threshold set for the comparator on the ILIM pin has been crossed.
1 = input voltage, input current, or input power fault or warning.
Description
1 = one of the two voltage dividers is probably disconnected or malfunctioning.
1 = the threshold set for the comparator on the OVP pin has been crossed.
1 = output voltage is below the VOUT_UV_FAULT_LIMIT (Register 0x44).
1 = output voltage is below the VOUT_UV_WARN_LIMIT (Register 0x43).
1 = output voltage is above the VOUT_OV_WARN_LIMIT (Register 0x42).
1 = output voltage is above the VOUT_OV_FAULT_LIMIT (Register 0x40).
General output overvoltage fault: this flag is a combination (OR) of any output overvoltage flag
(Register 0x7A, Bit 7 and Register 0xFE80, Bit 4 (FAST_OVP)).
1 = any fault on output voltage (overvoltage, undervoltage, fast OVP, or accurate OVP).
Description
Reserved.
1 = input power has dropped below the threshold for low power mode operation.
1 = an undervoltage condition is present on the VDD rail.
1 = INRUSH control relay is off.
