Is there a regulator on the VCC input of the DFR0601? I want to power it with 12 volts, but I cannot find any specification for VCC. It does say that control inputs are 4 or 5 volt compatible, but that does not answer the question.
Thanks, Russ
Sorry for the typo, I meant 3 or 5 volts, not 4 odr 5..
Hello russk2t and welcome to the DigiKey TechForum.
It appears that the signal control voltage will work with 3-5V. I see no indication that the signal control would work with a higher voltage.
Thank you Rick. I see the same, but it does not make sense. The VCC line connects to the only IC that is on the top side of the board, but that IC is unmarked and tests I have made do not show any regulation. I have a different H-Bridge that actually regulates down the voltage from the motor supply to be VCC. That is a much smarter arrangement. Unfortuantely it will not handle the current I need. It is going to be a real pain to use the DF0601 bridge because of the need for an external regulator to supply the +5v.
Also, the DF0601 is about the worst documented device I have ever seen. No VCC spec, no truth table, no real schematic, etc… Maybe DigiKey can ask the manufacturer for better documentation.
Regards, Russ
What documentation there is seems to suggest taking the control-side Vcc from an Arduino or similar type of board, which leads me to suspect it’s a direct connection with no regulation. This would not be an uncommon arrangement for such a device, though certainly not the only one found afield.
For better or worse, there are a number of “maker” class suppliers in the market serving primarily a hobby/education audience. Such a constituency is often unprepared to interpret formal technical specifications, and as a result the documentation from sources that cater to it tends to be characteristically incomplete and/or juvenile in nature. This is one of the means by which one may discern these lower-tier suppliers from others whose products and business models are more suitable to adoption for mass production.
