dSPIN Evaluation Software control two motors with separate chip selects
Posted on January 28, 2014 at 07:00Hi, I have an SPEVAL-PCC009V2 with EVAL-6470H setup controlling one stepper motor very effectively. I want to control two motors but would prefer to do this using separate chip selects for each L6470 instead of us...
Can L6206 be used as 4 half H bridges?
Posted on January 26, 2014 at 17:12I want to use the L6206 to drive 4 solenoids (one end of the solenoid each solenoid will be grounded) of 2.5amps each. Can this be done without damaging the IC. ? Also each of the bridges two halfs will not be driv...
No connection to STEVAL-PCC009V2
Posted on February 24, 2014 at 20:34Hi everybody,I'm trying to get the EVAL6470H working, but the problems are begining at the STEVAL-PCC009V2. I can't get any connection via the ''dSPIN Evaluation Tool'' to configure the L6470.I reflashed the firmw...
L7981 Datasheet Discrepancy
Posted on March 05, 2014 at 11:26Hi, I've started a new design using the L7981A and can't get the thing stable despite copying the reference layout. The datasheet is not consistent with regard to the feed forward constant 1/K. In Equation 15 it's...
ALTAIR04-900 spontaneously begins to oscilate and falls into burst mode
Posted on March 04, 2014 at 19:14I encountered some strange behavior of power supply based on ALTAIR04-900.Most of the time it works as expected but sometimes the voltage on COMP pin begin to oscilate with negative spikes by 0.2-0.4V each 5-7 micros...
HVLED815PFTR-based LED Driver minimun load
Posted on March 03, 2014 at 13:59Hi, I am involved in the design of a LED driver based on the HVLED815 IC. It works great with a load greater than 4W, but LEDs start blinking if the load is less than 3W (approx). So, my question is if there is any m...
buck-boost AC-DC convertion
Posted on February 24, 2014 at 15:45Good morning, we are looking for an configuration for our application LED driver. We are taking a look among your AN, for L6562 designing in buck-boost config. In the AN3111, at pg8, there is a not clear equation ...
Stepper control with L298 and L297
Posted on January 08, 2014 at 23:07Hi to all, my name is Cosimo and I need help about stepper driver.From an old printer I've get a bipolar stepper and now I'm trying to drive it with L298 and L297 configuration. Whitout the stepper the output of L2...
L6470 BEMF calculations
Posted on February 12, 2014 at 00:59Hi,Is there an online version of the BEMF compensation tool? I have a couple of boards from Sprakfun that are based on the L6470 but I'm having issues getting the performance out of the stepper motors that I thou...
L6470 motor power interlock
Posted on February 11, 2014 at 20:11I am using an L6470 controller in an application that requires an interlock circuit to stop motor rotation if the interlock switch opens. Is it possible to safely switch 24V power to the VSA and VSB pins off then ...
