Posted on May 20, 2017 at 12:13hi!I'm making a dual power supply (+/-12V) from +18V brick converter. To clean the DC-DC in the positive side I choose a LDL212, input is +13V from DC-DC and output is +12V.In addition to his own over-current protectio...
Posted on May 17, 2017 at 09:50I found a replacement for FGL60N100BNTD (TO-264) which is STGW40H120DF2 (TO-247) for my Inverter. At 50A peak current, however its a problem. Any reason or solution?
Posted on May 16, 2017 at 07:58Hello!I need information about values of the rms current which don't result in the open-circuiting of a transil diodes type SM6T and 1.5KE and about values of I2t for these devices.I need this informations to determin...
Posted on April 24, 2017 at 13:15I am using L9823 in my design to drive the outputs. I also want it to behave as input so that I can connect IO module. How can I use it as input?Thanks in advance

Posted on April 18, 2017 at 14:07Hi,When I am using the BEMF compensation configuration within the SPINFamily Evaluation Software, I input the Application Parameters and the Motor Parameters for my particular motor. When I press the �Evaluate� butto...
Posted on May 08, 2017 at 17:03Why does my BLDC motor stop during acceleration 2 ? Hello,I bought a STSPIN32F0 and i try to run this board with a BLDC Motor. But the first 3-4 seconds is working then stops. The same problem with me onhttps://communi...
Posted on May 07, 2017 at 12:50An arm cortex-M0 MCU is adopted to drive the powetstep01.The initialization of SPI is done including CS, SDO, SDI, CK,BUSY, STBY.Here is the problem, I want the step motor run, so I write this:CS=low;//chip selectSPI1_...
Posted on May 04, 2017 at 18:20Hi,We are working in a project using Viper26ln to generate a 3.3V (250 mA maximum current) from an AC 220 line using buck topology because we want our circuit as compact as possible, so we avoid using transformers.We ...
Posted on April 19, 2017 at 11:00Hello,I'm using the EVAL6472H evaluation kit to experiment with the L6472 driver. I'm having trouble with the hold current setting, when is set the hold current to 200 mA for example, only 70 to 100 mA flows through ...
