Over-Voltage Detection Control and Status
Over-Current Detection Control and Status
Over-Load Detection Control and Status
Enable Over-Voltage Detector On Line-Side Device
0 = Over Voltage Detector not enabled.
1 = Over Voltage Detector enabled (not latched). Over voltage detector
is enabled if ENOVD, ENFEL and ENNOM all equal 1.
Over-Voltage Detector On Line-Side Device
0 = Over Voltage condition is not detected at RGP/RGN inputs.
1 = Over Voltage Condition is detected at RGP/RGN inputs.
Over-Voltage Threshold Setting
0 = Over Voltage Threshold is 0.6 Vpk at the chip or 60 Vp on the line.
1 = Over Voltage Threshold is 0.7 Vpk at the chip or 70 Vp on the line.
Enable Over-Load Detector
0 = Over Load Detector is not enabled.
1 = Over Load Detector is enabled (not latched).
Over-Load Detector
0 = Over-Load condition is not detected.
1 = Over-Load condition detected. Asserted when the line voltage
exceeds 3.5 Vpk typically. OLDET is performed partially in analog
domain and partially in digital domain. OLDET is asserted when the
delta from aux A/D between two consecutive DCI samples is greater
than 76.
Enable Over-Current Detector On Line-Side Device
0 = Over-Current Detector is not enabled. (Default)
1 = Over-Current Detector is enabled.
Over-Current (I) Detector On Line-Side Device
0 = Over-Current (I) condition is not detected.
1 = Over-Current (I) condition is detected at the DCS pin when Loop
Current is > 125 mA if ILM=0, or > 55 mA if ILM=1.
