Hello everyone,
I am trying to desing a single supply current amplifier to drive a motor. The fact is that I don't want to use a H bridge. I have been using a AB class amp,
78% efficient
but it requires two bias.
You mean plus and minus supplies?
If I want the motor to turn on clockwise direction I should enable two transistors, and if want to turn on the other direction should enable the other two transistors.
