Configurable wireless charging transmit and receive monitoring device

A configurable transmit/receive (TX/RX) device for driving and receiving signals between at least two coils in an array of coils comprising:

• N inputs and N outputs (I/Os) that share the same respective N input and N output (N I/O) connections, wherein N is a positive integer greater than 1;
• an analog multiplexer having N mux inputs each connected to a respective one of the N I/O connections, the analog multiplexer further comprising M mux outputs, where M<N, the analog multiplexer configured to direct M AC input signals from each one of M selected ones of the N mux inputs to respective M mux outputs when the analog multiplexer is enabled;
• M receiver circuits each configured to receive a respective one of the selected AC input signals from respective M mux outputs and convert the respective selected AC input signal to one of M respective digital signals;
• a digital signal processor circuit (DSP) configured to process each of the M respective digital signals in accordance with a predetermined DSP configuration and output processed data adapted for use by an external device;
• a pulse width modulation (PWM) generator configured to output PWM signals in accordance with a PWM control signal;
• N gate drivers connected such that each respective one of the N gate drivers receives a PWM signal from the PWM generator, each respective one of the N gate drivers further receives one of N respective gate driver enable signals, each gate driver being configured to transmit an AC signal relative to its received PWM signal to the respective I/O connection only when enabled by its respective one of the N gate driver enable signals;
• a control portion configured to provide mux enable and mux select signals to the analog multiplexer and to provide the N respective gate driver enable signals to respective ones of the N gate drivers in accordance with the predetermined configuration and such that when the analog multiplexer is not enabled by the mux enable signal any of the N gate drivers can be enabled by the N respective gate driver signals, and such that when the analog multiplexer is enabled by the analog mux enable signal and the mux select signal designates the M selected ones of the N mux inputs, then any of the N gate drivers can be enabled by the N respective gate driver enable signals except for the M gate drivers that are respective to the M selected ones of the N mux inputs.
