Hello, We are using similar design of STEVAL-ISA203V1 with different transformer: CoilCraft POE600F-12LD. We see that there is very high current on the shunt resistors.

The peak on the resistors is about 2V, and we are using 3 parallel 0.1ohm resistors -> causing the device not working and infinity retries.We made a lot of experiments but for now, without any success.Any suggestions?I didn't find the datasheet of Co...

We have a requirement of power line communication temperature data measurement by 7580 IC Nucleo board. Initially we found this is very supportive, but the same time we found the ST board programming is bit difficult. Hence, now we are using Arduino board

STC3115 RemTime stays -1

Hello Everyone,I am using an STC3115 for managing the NCR18650B battery in my application. (In this setup the temperature measurement is not used because the battery doesn't have a THM pin. That's why the temperature value is 180.)My problem is the ...

Resolved! STSPIN840 PWM and PH signal management

For PH 0 & PWM 1, is the current OUT1 -> OUT2 correct?I think the picture below is an act for the above case. If my guess is wrong, how do I rotate the motor in the reverse direction?

STPM34 primary voltage/current reading issue.

Hi,So I got myself an EVALSTPM34 and decided to test it out with the evaluation software given by ST.According to the STPM34 datasheet/user manual to read the primary channel current and voltage I have to read the 48th register which contains the dat...

Resolved! How can we increase soft start time for VIPER319XDTR?

Dear sir, We have followed STEVAL-VP319X1B development board schematic for converting 110V/230V AC to 5V DC. In one of board we found that inrush current limiting resistor is burn out. We have followed same part number for resistor which is in develo...
