4.10 Voltage Sag-Detect Feature

The CS5461 includes Status Register bit, VSAG;

which indicates a sag in the power line voltage.

In order for sag condition to be identified, the mea-

sured VRMS must remain below a set sag threshold

level for a specified period of time.

To activate this feature, a voltage threshold value

must be specified in the Voltage Sag Level Register

(VSAGLevel); and a time-duration must be specified

in the Voltage Sag Duration Register (VSAGDura-

tion

). This Time Duration is specified in terms of

A/D cycles.

If VRMS is measured below the level specified in

the VSAGLevel Register for a duration of time great-

er than or equal to the number of A/D conversions

specified in the VSAGDuration Register, then the

VSAG bit in the Status Register will be asserted.
