I am trying to design a solid state SPDT switch around a powerpath IC but the only circuits I have come up with use MOSFETs and their body diode shorts the charger and battery when both are present.
Is it possible at all to make the following solid state SPDT (current directions allowed are shown with arrows) with MOSFETs? In any case, how can I make this switch (using bipolar transistors I assume?)?
Ideally I would like to short something to select between the two positions, but I can take care of the design of the control (I hope no charge pump is necessary).
Note: the load current is 10A and the charge current is 2A. The voltage is ~15V.
