I want to use two internal comparators to monitor current in a circuit. When the current gets above a level I want to turn off my switch, when the current falls below a level I want to turn on the switch. This needs to be done at a speed that is to...

Posted on March 20, 2017 at 23:15I have a sensorless BLDC drive application where I need to get near 100% duty cycle on the power PWM while spinning at about 1300Hz (21 pole pairs, 3700RPM). However it appears that the six-step library only samples...

Bob,I decided I could live with a constant current delta and went with your simplified single comparator with hysteresis concept.Thanks,Tim

Hi Bob,Thanks for the suggestion. What I failed to include in my description was that I was planning to set the threshold for each comparator with an on board DAC (one DAC for each comparator). That will give me independent control over peak curren...
