I've briefly looked at including an H-Bridge circuit in one of my designs and I see that most (if not all) have N-Type transistors (either Darlington or MosFets). This however needs two separate control signals to turn one half of the circuit on while the other is off.
Would the following circuit work? The theory (in my head at least) is that when the "Motor-Direction" signal is high N-Type Transistors T2 and T3 would be enabled while P-Type transistors T4 and T1 are disabled. Alternatively When the same signal is Low the opposite would happen. T5 would simply cut the power to the entire circuit and allow the motor to slow down and stop via the "Motor-Enable" line. I get that you would not have the Motor-Stop or fast reverse capabilities, but for a simple circuit that doesn't need that, would this not work just fine?
