Hi
I want to use a L6235 to control a BLDC motor, but do not have a micro to control the loop. Micro not an option. The are two options I have is to use an integrator as per datasheet or use app note DT0001 mention using the Tacho output and the FWD/REV.
The worry I have is the changing direction and braking will cause overheating and back power. The brake will be static, will the L6235 cope or do I need to add extra chopper circuit to deal with this? which way would be best? my system has two hall sensors at each end for end detects. There is no rotation senor at present, but would a rotation with a PWM a good idea and control the fwd/rew as in DT0001?
cheers
