Resolved! measure motor load torque using the FOC Iq current?
I would like to measure motor load torque using the FOC Iq current. Am I correct that torque should equal Iq*Kt. I am using the ST Motor Control SDK 5.4. I have characterized the Kt of my motor. I calculate Iq [mA] = Iq_s16 * VDD [mV/(Rshunt*Gain*655...
VIPER06 device marking
Please advise me where I can find the device marking for VIPER06HN. I was expecting to find it in the datasheet but it doesn't appear to be in there.What is the meaning for CHN on the top right side and for F04250 on the bottom right?Thank you.Paolo

Dear all, I would like to inquire about this part L9026-YO-TR, there is a character “ES” on the top marking, what does this mean? Best regards,cassie
Power Backup by Super capacitor
hi ,Aiming to have few minutes power back up for STM32 mcu with SD card incase main supply 5v goes OFF condition . Timer added for capacitor charging time since initial current is will be little high .The above is setup enough ? or something s...
STPM34 UART communication with ESP32
I have developed code in arduino IDE , I am only getting the output receive from UART 04000A075 . I understand that this is the default value in register DSP_CR1. Could someone please tell me what does this mean.I hereby provide the code for receivin...
Replace L6569 in an electronic ballast with L6571
Hello,Can I directly replace L6569 with L6571 High Voltage Half Bridge Driver with oscillator?I've notice that in L6571 doesn't have the internal bootstrap driver.Thanks.
EVAL6498L Evaluation Board
Moved from Feedback forum.I am exploring the possibility of using the EVAL6498L Evaluation Board to reverse the polarity of a DC bias in my circuit, and I would like to confirm whether it suits my application.Application Details:Objective: To dynamic...
PowerSTEP01, Sensorless Stall detection vs Overcurrent detection
I don't really understand how these two functionalities differ. One is measuring on both low side and high side, the other one only on low side.The available threshold values are the same in both cases.When would you use OCD_TH and not STALL_TH, and...
Resolved! VN9D5D20FN operating with Vcc 5v
Hello,We are looking to use VN9D5D20FN (SPI management and monitoring) as power distribution solution for our product. There are 4 channels which are fed from common output of a buck converter. The buck has 5V 3.2A max output and that goes into VN9D5...
Resolved! What is the maximum error of STPM32?
Hello,in the Datasheet of the STPM32 the accuracy of the active power is 0,1% error over 500:1 dynamic range.Is this the best case error or the maximum error of the enerqy measurement after calibration?What does the dynamic range of 5000:1 mean?
