BASIC APPLICATION

RECOMMENDATIONS

7.1

Typical Application Examples

For power strip power metering applications, such as

the MCP3914 application referenced in Figure 7-1, it

can be used as a starting point for MCP3913

applications.The most common solution is to use one

channel for voltage measurement and the rest of the

channels for current measurement. Since all current

lines are at the same potential, shunts can be used as

current sensors, even if they do not provide any

galvanic isolation.

Since all channels are identical in the MCP3913, any

channel can be chosen as the voltage channel (prefer-

ably CH0 or CH5 since they are on the edges and can

lead to a cleaner layout).

for MCP3913 applications).

For polyphase metering applications, such as three-

phase meters, it is recommended to use a current

sensor that provides galvanic isolations: current

transformers, Rogowski coils, Hall sensors, etc.
