Data Sheet
SAG Monitor PSM Interrupt
The ADE5166/ADE5169/ADE5566/ADE5569 energy measure-
ment DSP monitors the ac voltage input at the V P and V N input
pins. The SAGLVL register (Address 0x14) is used to set the thresh-
old for a line voltage SAG event. The FSAG bit (Bit 5) in the
power management interrupt flag SFR (IPSMF, Address 0xF8)
is set if the line voltage stays below the level set in the SAGLVL
register for the number of line cycles set in the SAGCYC register
(Address 0x13). See the Line Voltage SAG Detection section
for more information. Setting the ESAG bit (Bit 5) in the power
management interrupt enable SFR (IPSME, Address 0xEC)
enables this event to generate a PSM interrupt.
USING THE POWER SUPPLY FEATURES
In an energy meter application, the 3.3 V power supply (V DD )
is typically generated from the ac line voltage and regulated to
3.3 V by a voltage regulator IC. The preregulated dc voltage,
typically 5 V to 12 V, can be connected to V DCIN through a
resistor divider. A 3.6 V battery can be connected to V BAT .
ADE5166/ADE5169/ADE5566/ADE5569
Figure 34 shows how the ADE5166/ADE5169/ADE5566/
ADE5569 power supply inputs are set up in this application.
Figure 35 shows the sequence of events that occurs if the main
power supply generated by the PSU starts to fail in the power
meter application shown in Figure 34. The SAG detection can
provide the earliest warning of a potential problem on V DD .
When a SAG event occurs, user code can be configured to back
up data and prepare for battery switchover, if desired. The rela-
tive spacing of these interrupts depends on the design of the
power supply.
Figure 36 shows the sequence of events that occurs if the main
power supply starts to fail in the power meter application shown
in Figure 34, with battery switchover on low V DCIN or low V DD
enabled.
Finally, the transition between V DD and V BAT and the different
power supply modes (see the Operating Modes section) are
represented in Figure 37 and Figure 38.

Description
Time between when V DCIN goes below 1.2 V and when FVDCIN is raised.
Time between when V DD falls below 2.75 V and when battery switchover occurs.
Time between when V DCIN falls below 1.2 V and when battery switchover occurs if V DCIN is enabled to cause
battery switchover.
Time between when power supply restore conditions are met (V DCIN > 1.2 V and V DD > 2.75 V if the BATPRG
bits = 0b01, or V DD > 2.75 V if the BATPRG bits = 0b00) and when V SWOUT switches to V DD .
