7.3.5 Phase Detection

The AFE3010 monitors power line signal phase at any given time through the PH and SCR_TST pins. Both pins are clamped to VDD through internal clamping diodes. The PH pin is connected directly to the HOT power line. This enables the device to monitor the power signal instantaneously. Phase measurement is critical for faster and accurate response to system fault conditions. The SCR_TST pin measures the phase after the rectifying diode.
