Resolved! VN751S Switch Off State and Short Circuit Detection

Hi,I will use VN751S. However, I have a problem. I use feedback to detect open load condition. Use of voltage divider resistors and vn751 are attached.The problem is; For 24v, the result of the voltage division should be about 19V, but when you creat...

Recently I have bought STEVAL-SPIN3202 board, I have a specific bldc motor which i want to drive. In 6step algorithm , I want to edit the sequence of commutation according to the hall sensor inputs

Please let me know if the board automatically detects the sequence for excitation or do we need to edit in the firmware, if we need to edit it in the firmware in which section I need to edit the sequence in 6step library.

Resolved! Minimum duty cycle on a STSPIN240

Hello,As it is written in the datasheet, the propagation delay (Tpwm/d(on)) is 125ns. Does it means that if my PWM has a duty cycle less than 125 ns, the output will stay low? Or it is just a delay before seen my output getting high?Regards,Hugo

STSPIN32F0A why so poor cpu performance?

The STSPIN series is being touted to be able to do FOC but the embedded STM32F031 is hardly a mathematical genious. Being severely limited in clockrate as well makes proper FOC at any useable frequency for larger motors very hard.I can see how FOC fo...
