Resolved! STDRIVE 101 ENx Pin
Dear ST community I would like to use STDRIVE 101 similar to STEVAL-POOL4A board (s. schematic above). But to reduce number of PWM pins used I'd like to pull all the ENx pins to VDD (e.g. +3.3V) and drive only INx's pins by an advanced timer. Accord...
L6986 - Output voltage problem
Hello,I have a problem with the output voltage of 3.3VWith input power up to 6V everything is fine. But when I increase the voltage up to 24V, the output voltage slowly changes from 3,3V to 2,8V. The load is about 50mAI can't figure out what the prob...
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
part L9026-YO-TR marking confirmation
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...
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...
