9.2.1.2.1 Sense Capacitors

The sense pins of the TPSF12C3 feed into a high-pass filter and signal combiner within the IC, which rejects the line-frequency and DM components of the power line voltages, extracting the high-frequency CM component.

The sense pins externally interface to the power lines using Y-rated capacitors, designated as CSEN1, CSEN2, CSEN3 and CSEN4 in Figure 9-2. Choose Y2-rated sense capacitors of 680 pF, 300 VAC in this application to establish voltages at the SENSE pins of less than 1-V peak-to-peak when operating at maximum line voltage.
