Not quite no, it cant switch the open fet at low speed so the motor wont turn unless you spin it to help it on its way, had a few like this, once its up and running the other fets do the work so yeah this is right once its up and running  |
I was only quoting what would happen if there were say 3 FETs per output and only one was open circuit drain to source. As they are in parallel, the other 2 would still work and drive the motor as normally but would just get warmer. This was the case years ago with brushed ESCs.
