Hi there;
I've designed an h-bridge.
It is normal when i use for only one direction unless connect the other port.
This means that when i connect the IC to only R2, (R1 is not connected)
when this port is +5V, motor runs.
when this is 0V, motor stops. There is no problem.
Problem is that while connect other port and it is reverse of the other.
situation is this:
to R2 is +5V, to R1 0V. Motor doesn't turn. (or vice versa)
Also, R3 and R4 heat up.
I couldnt see how current flows. Can anybody do?
Circuit is driven L297.
