sorry for the late reply ( is the forum server giving problems? cant seem to log on)
Im not really good in my electronics, my looking at the new circuit u guys pain-stakingly posted, please inform me if im wrong about this.
When LEFT pic input is HIGH, Q1 would be ON. While RIGHT pic input is LOW, Q4 is ON. Then, current flows from left to right.
If LEFT PIC and RIGHT PIC is LOW, are both Q3 and Q4 ON? (pls correct me about this, i thought that this wasnt allowed for H-bridges)
Furthermore, im limited to a single PWM channel Another thing to note is I would be using standard mosfets except for the logic level mosfet i posted earlier located at GND. Is putting a Logic level mosfet at the GND an unwise move?
LAstly, in the circuit u proposed, i dont get this part. What is this for?
THX alot. u guys are great help
