STEVAL-PCC009V2
Posted on March 21, 2013 at 12:06I load down my own program to PCC009V2 ,after that i found i can't use the PC GUI to control the L6470 ,for the mistake is i can't connect the pcc009V2. why this happen ? Is that in the PCC009V2 had write some specia...
No Markings in L6390, L6386
Posted on July 26, 2013 at 05:37We bought IGBT driver ICs, from element14.. L6388ED, L6390, L6386...all those ICs dont have any markings to find, which pin is No.1. Usually all ICs have dot mark to indicate PIN.NO.1, or U mark at the top of IC. But...
L6470 loosing steps
Posted on July 16, 2013 at 16:10Hello, I am evaluating the L6470 as replacement for a discontinued chip, which is used in our application in the moment. I have to reach high speed (2500 step/s), however when going above 800 step/s the motor looses ...
easySpin.c's easySPIN_Write_Byte
Posted on July 09, 2013 at 03:09Accoding to the IC datasheet, the number of bytes during a spi transfer can be 1 to 3 bytes, with a single chip select at the start..however, the sample code (for set/get parameters) calls easySPIN_Write_Byte for EVER...
L5988D problem
Posted on July 30, 2013 at 10:46I need a DC-DC converter from 12V to 3.3V and 4A. So I decided for swiching regulator L5988D.My circuit is the same as in https://www.dropbox.com/s/1fca0waylp8x795/switcher.png.My problem is, that switcher begins turn...
VIPer53 with a wrong protection mode
Posted on July 30, 2013 at 09:56I used VIPer53 in my product,I found that some of them entered into overheat （about 65℃） protection mode after running 70~180 mins at out power was 17W, and my design output power is 30W at Vin=220Vac. Change another ...
replacement for l4909
Posted on July 21, 2013 at 14:57I wanna ask ST for replacement for LDO with multiple outputs L4909I read that this product was obsolete and i wanna use one with the similar function So, can you provide me with the replacement for this part ?Thanks
IGBT gate Driver
Posted on July 19, 2013 at 06:33Hello...I want to chop the DC so that 585VDC into 400VDC. I dont know How to Connect the gate of IGBT w.r.t Emitter. Because Emitter here is not at zero or Grounded, Its floating. The ground of Microcontroller connect...
L6482H
Posted on June 19, 2013 at 16:54Hi,I'm using L6482H in my board. I changed original MOSFET (eval6482h) and now I use STP35NF10.My board work ok with default parameters.Im working in STEP_MODE with 1/8 microstep. Rsense = 0.1R / VS = 43VAt low revol...
Additional analog inputs while using FOC library
Posted on July 17, 2013 at 12:54Hi, I'm planing to use the FOC library (using v3.3) for a brushless motor. The library takes care itself for the input for current (dual insulated current sensor), voltage, temperature, but it takes all the two ADC of...
