ST1PS03 is taking a while to reach the programmed voltage...

I designed a simple breakout to test the ST1PS03A and left PGD and the entire AUX block unconnected including AUX (enable). I am getting the output voltages expected from the D0/D1/D2 truth table but it takes tens of seconds to get there. I am wonder...

Resolved! I am using STM32 based control board to control a pmsm. I am using a UCC27712 gate driver IC. Observing PWM pulses on scope, they seem to overlap and as duty ratio increases over lap increases. Is the "UCC27712 gate driver IC" is compatible with STM32??

In the IC VNQ7004SY ,There is PWM control through the SPI using register. I could not find the relevant details in datasheet about register. Can anyone help me how is it possible?

Hello, please tell me how to use l9788 to do low side PWM output?

may I ask that what is the difference between L9369-TR-TX2 and L9369-TR-TXHQ?

I am using split capacitors in my LLC design, any suggestions for capacitor divider based current feedback applicable for L6599 or LL6699 IC's. Can I use same circuits mentioned in Datasheets ?

Resolved! Where can I get the firmware STSW-SPIN3201 for STEVAL-SPIN3201. The link found in the community is broken. https://www.st.com/content/st_com/en/products/embedded-software/motor-control-ic-software/stsw-spin3201.html

Thank you.

Resolved! I´m trying to calculate my LD1086PUR to output 5v and 3.3V

I´m trying to calculate my LD1086PUR to output 5v and 3.3V for an ESP32 and somehow can´t get it right. Does someone have an idea which resistor I should use or how I can calculate the resistor? I tried the Vo=Vref * (1+R2/R1) but it doesn't seem to ...
