Is it crazy to think that I could use a combination of MOSFETs and BJTs as the switching elements in a single H-Bridge?
In an application for a radio controlled car, which would spend most of its time going forward, could I use MOSFETs for the forward control "arm" of the bridge and BJTs for the reverse "arm".
I am thinking primarily of the switching element costs, in that the cost of the bridge could be reduced significantly if BJTs could replace MOSFETs for one half of the bridge.
One complication might be braking, which I originally intended on achieving by switching on both of the low side MOSFETs together and, in the scenario proposed above, would now involve switching on a low side MOSFET and a low side BJT together.
Thought, comments welcome.
Thanks
