1. An apparatus for energy switching control, wherein the apparatus comprises a control section and a transfer section, wherein the transfer section comprises:
a power input port to receive energy;
a power output port; and
a transfer device adapted to transfer energy from the power input port to the power output port when the transfer device is enabled;
wherein the control section comprises:
a control input port to receive an enable input signal;
a control output port to output an enable output signal;
a comparator adapted to compare a voltage of an energy device with a reference voltage to generate a comparator output;
an XOR logic gate adapted to receive the comparator output and a function select signal associated with the apparatus to generate an XOR output; and
a demultiplexer comprising:
a demultiplexer input coupled to the enable input signal;
a select control signal responsive to the XOR output and to assertion of the enable input signal;
a positivity output signal generated by ANDing the demultiplexer input with the select control signal, and
a negativity output signal generated by ANDing the demultiplexer input with an inverse of the select control signal; wherein
one of the positivity output signal or the negativity output signal is coupled to the transfer device, and
the other one of the positivity output signal or the negativity output signal is coupled to the enable output signal to enable a second switching control apparatus for energy switching control.
