Resolved! HI, I'm testing STEVAL-ISA178V1 evaluation board. When I connect the DC output to the oscilloscope, it gets short circuited.

The fuse of the AC mains gets switched off. I tried to connect the oscilloscope through a 10k resistor and the same behavior was observed. However, I could verify that the switching regulator works fine by measuring the voltage with a voltmeter. Both...

Resolved! STEVAL-PTOOL2V1, STSPIN32F0252, the current cannot be read below 1A

For example current detection, HW:STEVAL-PTOOL2V1SW:en.stsw-ptool2v1_v1.0.0.zipIt will be abnormal when it is about 4A or below, and it cannot read below 1A.About 4A or more (to more than 10A) can be detected normally,Could you please help me where m...

Resolved! Hi all can ı make design 1/10 or 1/20 microstep resulation with stspin820 stepper motor driver of st microelectronic by manipulate vref input and R current sensing resistance

I wanna step motor driver by stpin820 device without 1/2 ....1/256 for example 1/20 e.t.c manupilate resistance for ıc current sensing and vref input thanks

The method to alter the speed of the motor with EVAL6235Q and how does the external speed loop control work?

Resolved! Has any information on the PPAK SMD PCB land pattern . Im trying to use a LF50AB regulator and I cant find a PCB land pattern drawing anywhere , searched STM etc Thanks Dave

I have a project of writing a report on power consumed by electronic devices specially computers and laptops along with connected accessories. How can we optimize the power management as the use of electricity by such devices is continuously increasing?

I am using STUSB4710AQTR in a USB C PD. I designed my circuit based on STEVAL-ISC004V1 schematic, but I’d like to use A5973ADTR instead of ST1S14PHR. can I use A5973ADTR the same way that ST1S14PHR is used in this circuit?

Resolved! Can anyone please explain to me how to read this graph? what is the meaning of the symbols used here (triangle,diamond and square) and how to read the equation as IDLIM seems to be cancelling from both sides? This is a figure from the datasheet of VIPER28

The location of dot for No.1 on the surface of the product is different.Seems to have markings are rotated 90 degrees differently from existing products. Is there anything special about the production lot marked on the label below?

Resolved! EVAL6498L Bootstrap diode internal to the chip?

Hi there, regarding EVAL6498L, is it necessary to mount the diode D1 (represented as not mounted in the schematic diagram)? or is D1 not necessary because the bootstrap supply diode is already included inside the 6498 integrated circuit?Thank you
