Posted on May 09, 2013 at 10:12I put in a technical support request on this but no response. I'm running a Viper16 in a simple non-isolated buck configuration as per the data sheet. There is a spark ignitor on the board and sometimes when the spark ...
Posted on May 11, 2014 at 10:57I'm evaluating L99ASC03 to control a brushless motor which drives a propeller. A series of LiPo accumulators will supply the board. The supply voltage is about 7V when 2 LiPo accumulators are used. When more LiPo accum...
Posted on May 13, 2014 at 12:06Hi everyone, I'm driving 3 stepper motors in a daisy chain configuration. In order to start and stop all 3 motors the same time, I'm calculating the speed and acceleration values for each motor and write down the confi...
Posted on May 09, 2014 at 11:29Hi,I found an AC-DC evaluation board STEVAL-ISA018V1 which uses L6599 designed for 24V 6A with cut-off at 10A (thermal). I want to modify it for 8-10A (at 24V)operation. How to enhance the current rating? Which compone...
Posted on April 23, 2014 at 16:19I have followed the Viper16 design tool and have followed the recommended components. The result is a voltage that is lower than expected (4.5v when expecting 5v) and dropping voltage as current increased from 5mA to...
Posted on April 15, 2014 at 17:57I'm using TIM1 for a 6-step motor control on a STM32F2xx. According of the table 4 in DM0004234 application note, I update OCxE and OCxNE at each commutation, to select a new step. When OCxE = 0 and OCxNE = 0, the ou...
Posted on April 27, 2014 at 22:25hi i want repair a board with an unknown ic.what is this ic? please help mehttp://i60.tinypic.com/28we9v9.jpg
Posted on April 26, 2014 at 08:51Hi, We have already design 12 volt 360mAmp current output non isolated power supply. But rigth noe we have increase current capacity in our exiting design. please let us know how to increase current capacity and how ...
Posted on April 25, 2014 at 17:09We want to run the stepper with as little current as possible. But then there's the risk to loos step if hoigher torque is neede (becuase of dust, friction,...). Is it possible to detect higher torque and increase ph...
Posted on April 21, 2014 at 15:48I am looking for a PCB footprint for the L6229Q VFQFPN 5 x 5 x 1.0 32 lead 0.050 pitch package. Is there a footprint available that has been used successfully and is available to download anywhere?
