Posted on March 17, 2016 at 08:23Hi there,I have built my own circuits to drive a BLDC motor. So far I have managed to get an RC BLDC motor working quite smoothly in open loop. However my 1kW motor is not running good at all, it cgs at lows speed an...
Posted on January 18, 2016 at 16:37Dear all,i'm building an application using STM32F303 and FOC Library 4.1.We're using a custom board with three shunt topology.PWD is 16kHZ and the motor runs up to 26k rpm. I use hall sensors for the statup phase a...

Posted on March 31, 2016 at 15:28I'd like to know if the STL62P3LLH6 P-channel MOSFET's Safe Operating Area chart is correct in http://www.st.com/web/en/resource/technical/document/datasheet/DM00105886.pdfhttp://www.st.com/web/en/resource/technical/...
Posted on March 29, 2016 at 12:45Hi, I attached my schematic to help in my discussion. I made a huge mistake by selecting a Linear Regulator U200: (12Vin - 5Vout). Roughly I'm drawing about 1.5Amps, therefore my power dissipated across the IC is (...
Posted on March 08, 2016 at 05:48Hi, I'm trying to build a constant current LED driver using the ST1CC40. I built a prototype version and noticed that with no load attached, the entire Vin (in my case its 12V) is seen at the output. Is this normal? ...
Posted on March 28, 2016 at 07:43Hello! I want to ask a question about chip PFC L4984D.1. Calculate the inductor according to datasheet. When the input voltage is greater than 200 volts, the inductor begins to make noise, heavily distorted input cur...
Posted on March 25, 2016 at 14:04I am working on an application where I need to use three L6472 ICs on the same board. I am wondering what external components can be shared between 2 or 3 L6472's. For example, can one cap elec 100uf 63V on the VS in...
Posted on January 18, 2016 at 13:21I think there is a mistake in the scheme: Checking data sheet (and a board built by myself), the red line (2) is wrong, and it is necessary the blue line (1). I have destroyed 3 L6482 chips before to find out what ...
Posted on March 18, 2016 at 20:15In the datasheet, Register 0 has 5 bits (P0-P4) that are defined as ''This bits control position of motor, e.g. 00000 step angle is 0, 01111 step angle is 180. There is no table which defines how to derive the other...
