I need a symmetrical MOSFET, i.e. the kind that would not conduct Source-Drain. Are there any? Or do all MOSFETs have body diode?
The circuit in question is attached. Transistor Q1 works as a load switch and will only be used in Drain-Source direction. However, transistor Q2 is a memory key. it either loads up gate of Q1 with charge or sinks charge to ground. Q2 is meant to separate Q1 from the ON/OFF circuit and is only activated when SYNC is positive.
