... From RING (Note) When the Ring Detect feature of SM8220 is not used, always connect RDIN and RDRC pins to the system ground level. This will cut excess current drain from VDD under the normal and power down mode of operation. This diagram example is desingned to adapt to the specifications of United States. ...
