TS339I

Hi, Team   We are facing issues with test process performed at ICT test station. We are testing driving current to detect Zener Clamp diode 8.2V, the units fail with 2.64688 volts, but this line is connected to comparator TS339I pin 5 that is not pow...

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...

STEVAL-DPSTPFC1 source code and BINARY code

hello,I have STEVAL-DPS334C1 and STEVAL-DPSTPFC1. I am trying to put PFC code on STEVAL-DPS334C1 again. I load bin file via stm32programmer. then STEVAL-DPS334C1 crashes. I need source code to find where the error is coming from. Or if you have any s...

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...

SPV1050 Mode Issue

I am designing a PV cell charging circuit with SPV1050.When the configuration is set to boost mode, I am curious what happens if a voltage higher than Veoc is applied to the PV cell.

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
