L6470 Motor Driver Kval Parameter
I'm using the AN4144 Application Note to program the parameters for the L6470 Motor Controller. It shows that the Kval correlates with the desired voltage, or the target current multiplied by the motors' resistance.but the only other reference to Iph...
I have a question about the microstep using the L6480 driver
I use L6480 stepping motor control driver. and I use microstep function (resolution 1/128)There was a problem that the motor did not move in a certain section when the motor was driven 1 step at a time with the microstep.This picture below is the par...
ISO808 reverse protection and maximum current. 2nd question Are the 0.01uF necessary?
Good Morning/Afternoon. Thanks for your time.I must use 2 ISO808TR in a project.Because of the large current requested (0.5 A * 8 *2 = 8 A or worse 0.7A *8 *2 = 11.2A) and the absence of heat dissipator (orange derating curve) I could not use a diode...
Resolved! EVALKIT-ROBOT-1 / MODBUS RTU / QUESTION
Hello CommunityI try to test the EVELKIT-ROBOT-1 using MODBUS RTU.I did it it's factory setting.After I had connect all the cables, I powered up the EVALKIT.Motor turned to its init position and stoped at some point. And Motor hold that position ...

i searched about the spice model of VNI8200XP (CAD resources ) to simulate with LTspice site but i couldn´t find it , so could you provide it.thanks in advance .
2N5551HR LCC-3 Package Pin Orientation
Looking at the 2N5551HR datasheet pages 7 - 9, it is misleading where pin 1 is located. If you look at the UB package on page 7, pin 1 seems to be on the opposite side to the ident and dot. Does this also mean the LCC-3 package is also wrong. Can ...
I'm using the STC4054 Li-ion single cell charger in a design, the CHRG pin is supposed to have a weak pull-down when not charging but the current drawn is higher than specs
In the STC4054 datasheet, it says the CHRG pin is supposed to have a weak pull-down of max 35uA when no battery is connected yet. However, with a 4.7Kohm pullup from that pin to 3.3v, I measure a 1.2v drop, which indicates about 250uA of current. Wit...
Help with nucleo board and pca9685 servo board
Hello everyone,I came here looking for help : I'm doing a project for an intership where i have to create an hexapod robot basically from the ground up, with particular interest in the electronics and programming part.As a main microcontroller, we ar...
Problems with STSPIN32G4. False overcurrents errors, and gd_nfault occurs. Bad soldering process?
Hi, we are facing a strange problem with your MCU + GD combo - STSPIN32G4. In general, about 60% of soldered ICs are not working properly, we test on the default firmware generated for EVSPIN32G4 and we get error "64 overcurrent" and / or gd_nfault a...
