I have the questions about bq500211 chip of wireless charging function, bq500211 chip has V-sense pin to detect transmitter input voltage and used it for efficiency calculations, but our circuit has two kinds of voltage of transmitters as 7V & 12V, should we use fixed 5V to separate voltage to give to V-sense? Or should we must set two different separating voltage systems for 7V & 12V of transmitters as V-sense pin? Does V-sense will adjust PWM parameter and inflect power transmit efficiency?
