L6235 internal logic and temperature ratings
Posted on May 14, 2014 at 18:21I have 2 questions that I've posted to online support but haven't received a response. (1) I need clarification on the BRAKE input function - does it always short the 3 HS mosfets, independent of the ENA signal? I have...
L6482 Speed issue
Posted on April 11, 2014 at 14:47Hi,I'm tring to use a L6482 using only speed (Run) command because we have to use the motor in speed mode. Acc/Del are on our control. Chip Acc/Del are set to infinite (0xFFF) and MIN_SPEED/MAX_SPEED at 0,0x3FF. STEP...
L6480 high current absorbtion
Posted on May 22, 2014 at 11:42Our application:We have a Stainless steel disc diameter 30 cm, thickness 1mm, coupled with a chain to a stepper motor. The mechanical reduction is 1.5 (means that speed disc is slower than motor speed). Speed range of ...

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...
