Hey guys i need to design a simple H-bridge that uses vcc=15V to run the a DC motor and use a 4.2V signal to drive the H-bridge forward and backward. and i've attached a pic of what i've tried so far but i've run into the problem of the top PNP transistors staying constantly on. i know it has got to do with the fact that my PNP emitter voltage is higher than my base voltage and as a result the transistor doesn't turn off.
i'm wondering if anyone could give me any advice on what i could do to the circuit to make it work?
any help would be appreciated. Thanks.
