Need help identifying the material of semiconductor SOA (safe operating area) for STPS3L40UF. Which material below? SiliconSilicon CarbideGallium NitrideOther
powerStep01 Active Position Tracking
Is there a way to read the motor position while it's moving, such as with a command like "run," "goto," "move," or any other command from the Powerstep01? Does the motor need to be stopped for the motor position to be read correctly? Currently, when ...
Resolved! Mystery IC number ?
Hello allI don't know if this is the right sub-forum, I chose the one that seemed the closest.I've been spending a bunch of time trying to find the part number of a seemingly simple IC, but just hitting walls. I've Googled using the manufacturers nam...
L9916 Programming Mode
We are evaluating the L9916 IC and need to test it with different settings. We are following the information in the Datasheet and the Programming App Note. We keep the IGN, PHASE and LAMP pins at 0V right until the moment we send the ignition sequenc...
Precision voltage reference with low 1/f noise
Hi all, I am looking for two voltage references to produce two rails ( positive and negative) with low frequency noise.The voltage reference does not need to have a tight output voltage accuracy and long term precision. It needs to be stable over a 1...
Resolved! LM317 adjustable voltage setting question
I'm reviewing the datasheet for the LM317 linear regulator, and it lists the equation for calculating voltage as:VO = VREF (1 + R2/R1) + IADJ R2If I plug in the numbers from my circuit (and neglect the error calculation), I get:1.25 * (1+(1400/400)) ...
L6566bh Flyback Startup failure
I have followed the design attached in PDF. It is from ST designsuit.I have used MYRRA 75032 flyback transformer. (Datasheet Attached)Optocoupler 140105146000 with CTRmin - 50%, CTRmax - 150%.So now problem is I am not able to get continuous Vout fro...
Explain RC filter of STGIB8CH60TS-E Smart Shutdown Circuit?
Hi everyone, I’m using the STGIB8CH60TS-E IPM in my motor drive design and trying to configure the smart shutdown (overcurrent protection) function using the CIN pin. As per the datasheet, the internal comparator reference voltage (Vref) is typically...
powerstep01 (stepper motor skipping steps after few hours of operation)
Which alarm to read if our motor skips steps while moving? The motor works fine for a period of time like for 4hours and then randomly starts to skip step while moving in forward direction whereas in backward direction it moves fine. We are using 1/4...
SPI ERROR BIT of Global Status Byte for VN9E30F Driver is getting triggered
Hello Team, We are using VN9E30F High Side Driver, when we try to communicate it through SPI, the SPI Error Bit of Global Status Byte is getting Set and Reset as well. We are Following Below Configuration for SPI:- Could anyone help me to verif...
