Description
1 = disconnect the output of the current balance block from the PWM outputs.
0 = connect the output of the current balance block to the PWM outputs.
0 = disable current balancing when the fast loop is triggered.
1 = enable current balancing when the fast loop is triggered.
It is recommended that this bit be set to 0.
Reserved.
1 = disable current balancing under low power mode if the output of the current balancing
block reaches the limit.
0 = enable current balancing under low power mode even if the output of the current
balancing block reaches the limit.
It is recommended that this bit be set to 1.
Reserved.
Description
1 = EEPROM is unlocked and its contents can be written.
1 = downloaded EEPROM contents are incorrect.
1 = fast loop compensation filter is in use.
1 = maximum modulation limit is reached.
1 = minimum modulation limit is reached.
1 = system is in soft start sequence; fast loop filter is in use.
Description
1 = general input undervoltage fault (same as Register 0x7C, Bit 4).
1 = VAC is lower than VIN_OFF (Register 0x36). This signal shuts down the power supply.
1 = input voltage on VAC is smaller than the value in VIN_UV_FAULT_LIMIT (Register 0x59).
1 = input voltage on VAC is smaller than the value in VIN_UV_WARN_LIMIT (Register 0x58).
1 = input voltage is higher than the high line threshold.
1 = VAC is lower than the value stored in VIN_ON (Register 0x35).
1 = communications, memory, or logic fault.
1 = an overvoltage condition is present on the VDD rail.
Description
1 = measured temperature is above the value of OT_WARN_LIMIT.
1 = measured temperature is above the value of OT_FAULT_LIMIT.
1 = temperature fault or warning.
1 = fault or warning not listed in Register 0x79, Bits[15:1].
1 = manufacturer-specific fault or warning (Register 0xFE80, Register 0xFE81, Register 0xFE82).
1 = PSON signal (hardware or software) is inactive.
Power good. This flag is a programmable combination of other internal flags and refers to the
condition of the output voltage. A value of 1 means that the output of the PGOOD pin is low.
This flag is a programmable combination of other internal flags and refers to the condition of
the input voltage. A value of 1 means that the output of the AC_OK pin is low.
1 = the resistor on the ADD pin has a value that can cause an error in the address assignment
(the address falls too close to the threshold between two addresses).
1 = external synchronization frequency is locked.
