6.3 Page 2 Registers

6.3.1 Voltage Sag Duration (VSAGduration, V2SAGduration) Registers

Address: 0 (VSAGduration), 8 (V2SAGduration)

Default = 0x000000

Voltage Sag Duration (VSAGduration, V2SAGduration) defines the number of instantaneous measurements utilized

to determine a sag event. Setting these register to zero will disable this feature. The value is represented in un-

signed notation. See Section 5.6 Sag and Fault Detect Feature on page 20

6.3.2 Current Fault Duration (ISAGduration, I2SAGduration) Registers

Address: 4 (ISAGduration), 12 (I2SAGduration)

Default = 0x000000

Current Fault Duration (ISAGduration, I2SAGduration) defines the number of instantaneous measurements utilized

to determine a sag event. Setting these register to zero will disable this feature. The value is represented in un-

signed notation. See Section 5.6 Sag and Fault Detect Feature on page 20.

6.3.3 Voltage Sag Level (VSAGlevel, V2SAGLevel) Registers

Address: 1 (VSAGlevel), 9 (V2SAGlevel)

Default = 0x000000

Voltage Sag Level (VSAGlevel), V2SAGlevel) defines the voltage level that the magnitude of input samples, aver-

aged over the sag duration, must fall below in order to register a sag condition. These value are represented in

unsigned notation and in the range of 0

≤ VSAG

level < 1.0 (0 ≤ V2SAGlevel < 1.0), with the binary point to the left

of the MSB. See Section 5.6 Sag and Fault Detect Feature on page 20.

6.3.4 Current Fault Level (ISAGlevel, I2SAGlevel) Registers

Address: 5 (ISAGlevel), 13 (I2SAGlevel)

Default = 0x000000

Current Fault Level (ISAGlevel, I2SAGlevel) defines the voltage level that the magnitude of input samples, aver-

aged over the fault duration, must fall below in order to register a fault condition. These value are represented

in unsigned notation and in the range of 0

≤ ISAG

level < 1.0 (0 ≤ I2SAGlevel < 1.0), with the binary point to the left

of the MSB. See Section 5.6 Sag and Fault Detect Feature on page 20.
