I am trying to understand how H-bridges work and have been looking at a lot of different designs.
Most designs use p-ch MOSFETS for the high side and n-ch for the low side.
From what I understand, n-ch current flows from D to S when switched on, and p-ch current flows from S to D when switched on.
I get how each one is switched on, makes sense.
What I am struggling to understand is, when I look at H-bridge schematics, the motor terminals are connected between the D of the p and n mosfets.
That makes sense to me on the p-ch side, where current flows from S to D, but not on the n-ch side where current flows from D to S.
I would think that the motor would be between the D on the p ch and the S on the n ch.
Can anyone tell me what I am missing?
