Power management

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

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

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

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
