I recently purchased a TB67H420FTG board to power a 24V DC gear motor. The board works well in my application but, as I am fairly new to electronics, I would like to understand more about the power circuit.
If I have reviewed the schematic properly, it seems to employ a p-channel MOSFET with a Zener diode for reverse polarity / battery protection. My question is whether or not this provides the same protection as a freewheel diode or whether I still need one across my motor.
Thanks in advance for any guidance.
