Viper16 Problems
Posted on May 21, 2014 at 01:24Hello, I am having problems with viper16, symptoms are identical to other people's posts. Power rises slowly and above set level (3.3v) . As soon as I power anything (microprocessor) voltage drops fast to 0v, if ciruit...
Viper 16 hangs up
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 ...
L99ASC03 internal voltage regulator
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...
Driving minimum speed with the L6480
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...
Viper16 Buck non-isolated
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...
PWM: drive output low in disabled mode
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...
L6229Q Footprint
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?
L6206 PWM on EN line blows EN line!
Posted on April 14, 2014 at 23:24I have a design with a L6206 driving two permanent magnet DC motors. With one motor, the chip is connected exactly like in the datasheet on pg. 18. It works fine. The other motor is almost identical except the IN lin...
Finding parameters for L6470
Posted on April 11, 2014 at 20:13I am quite novice when it comes to stepper motors and am having some difficulties. I am evaluating the L6470 to replace an old step/dir motor drive. The motor used is an Applied Motion HT17-075 nema17. Form the specs...
