Figure 9 shows the CS5462 configured to measure
power in a single-phase 2-wire system while oper-
ating in a single supply configuration. In this dia-
gram, the shunt resistor used to monitor the line
current is connected on the “Line” (hot) side of the
power mains. In most residential power metering
applications, the power meter’s current-sense

shunt resistor is intentionally placed on the hot side
of the power mains in order to detect a subscriber’s
attempt to steal power. In this type of shunt-resistor
configuration, the common-mode level of the
CS5462 must be referenced to the hot side of the
power line. This means that the common-mode po-
tential of the CS5462 will typically oscillate to very
high voltage levels, as well as very low voltage lev-
els, with respect to earth ground potential.
