Resolved! STSPIN840: Why does the En/Fault doesnt go to low if SNSA is higher than VrefA?
Hi All, I tested the motor driver STSPIN840. I'm able to limit the current through the motor. But i dont see the Fault Pin going down to zero if the driver limits the current. If i do a short circuit on the output the Fault Pin goes down to Zero. Wha...
Incorrect example files are on the ST website for STEVAL-ISA164 STNRG388A digital controller eval boards sup. I submitted a support support ticket, but if someone could create a simple example to fix missing Example 4 it would be greatly appreciated
I wasn't sure where to post this request for the STNRG digital control IC example files so Power Management is my guess.There is a link to download 5 sample files for the STLUX chip and 3 more for the STNRG digital controller eval boards. In the avai...
Resolved! Subject is MOC3021 : What is the typical control voltage ?
Il the decription of the datasheet we can read this text :They are designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115 VAC operationsBut in the Typical Application Circuit (figure 12)...
L7981 Random Dropouts
Hi, I'm looking for technical help on an L7981 voltage regulator issue. We have been using these for years in various designs with minimal issue. On a recent new prototype, I am having an issue I have never seen before, where on occasion the regulato...
How can I reduce L6472 Stepper Motor Noise due to harmonics?
I have a motor control PCB with x6 L6472PD stepper motor drivers on. 2 of the drivers are being used to drive NEMA17 "hybrid stepper" linear actuators that move a module along a linear guide. The two drive systems are laid out identically, and conven...
Measuring the frequency response of an optocoupler (e.g. PC817C) with different pull-up resistors using a Bode 100.
My test reference circuit is from Mr. Christophe Basso's book: "Designing Control Loops for Linear and Switching Power Supplies By A Tutorial Guide"The picture is showed as follow.Unfortunately, it may be a problem with my test circuit, or maybe the ...
