Posted on April 18, 2013 at 16:07HI , 1.can any one tell me how to PWM DC motor using L6205 ,via EN pin or INX pin ? 2.how can i make the motor coasting (in PWM OFF) ? for the Table in the Datasheet when EN=1, if IN1=0,IN2=1 => OUT1=GND...
Posted on April 02, 2013 at 02:13Hello.I've gone through the process of selecting part values for a few other dc/dc converters but I'm stumped with the steps to do so for the MC34063. I'm starting with 12V and converting to 5V and 3.3v so I just cop...
Posted on April 14, 2013 at 11:40yesterday, I tried board STEVAL-IHM027V1, and then a burst, the explosion is under IC former, when I check with a multimeter, pin 25 (positive dc input) and pin 21 (v phase output) to be short circuited? whether it ...
Posted on January 27, 2013 at 23:05Hello, I am trying to rotate my stepper motor 5000000 micro-steps (in 128 micro-steps mode) and its size is bigger than ABS_POS register size (it only has 22 bits in two's complement format). When the register over...
Posted on April 10, 2013 at 17:48Hello, The image below is a piece of PCB layout of a flyback converter. As the layout is important I inserted a picture. The red is copper on the top layer. Blue is copper bottom. Problem I had with this converter i...
Posted on March 28, 2013 at 16:31I am using the L4931 VLDO regulator in my circuit, to regulate form 12.5VDC input to 3.3VDCThe part number that I am using is the L4931ABDT33 with the correct input and output capacitors as stated in the datasheet te...
Posted on March 18, 2013 at 23:51What is the smallest RDS on value that will work with the L6480? How do I set the phase current to 2.3 amps?
Posted on March 06, 2013 at 16:20I am trying to get the L6480 Demo board communicating with the L6480 Evaluation software using the the STEVAL-PCC009V2. I have tried in Windows 7 and Windows XP and was able to get the driver for the PCC0009V2 loade...
Posted on October 01, 2012 at 11:52Hi, I'm new to this forum, because I really need some help designing a driver board for a stepper motor. The motor has to phases, 1A per phase, 8.6V and will be controlled over A+/- and B+/- (bipolar). The board wi...
Posted on August 17, 2012 at 16:05Hi, I have tested over 20+ boards that was designed to take L6926 regulators and find that some of the regulators abruptly go into thermal shutdown mode. I think it is thermal shutdown because it tries to spring bac...
