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...

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...

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...
Investigating the Cause of Empty Measurement Fields in EVAL3PHISO Kit's STPM005 Software
I am attempting to establish a connection between the EVAL3PHISO kit and its accompanying software, the STPM005 GUI. To power up the board, I am utilizing a USB cable connected to my laptop. The illuminated green LED on the kit verifies that the boar...
