BQ500110 Device Dual Communications Channel

Ron,

Two channels of communication are redundant to each other.  Some redundancy helps when secondary-side impedance-modulation communication excibits nulls of communication -- points at which amplitude of the signal received on the primary side drops to very low levels.  It was experimantaly shown that having two channels with different detecting approach can help better resolve communication null problems.  One of the channels is a peak-detector and another is a synchrronous detector.
