Power management

Resolved! STEF01 - what is the equivalent circuit of the ENABLE/FAULT pin ?

The ENABLE/FAULT pin delivers back a voltage that provides the part status (Table 6 of the DS).It is said that OK = 5V; thermal fault = 1.4V; power protection = 0V.As this pin must be directly connected to a 3.3V FPGA pin, I made some measurements wi...

Resolved! Schematic x-nucleo-ihm08m1 does not seem to the latest

Hello,I have the x-nucleo-ihm08m1 board and looking into the schematic I do not see the potentiometer R42 in there.I bought my board recently from mouser.The schematic i downloaded from the web page of the board (attached).Thanks in advance.

Resolved! Regarding Spikes in Phases in BLDC Controller

Hello All, I'm developing 48Volt 700Watt BLDC Motor Controller Using STM32 Controller. I didn't use STM Motor Control Workbench Tool for this Project. I developed my own library and source code for this project. When motor is running initial spikes i...

Resolved! I want to knwo what is the Iout of VN7140, and what is the meanning of the "Iout - Internally limited", why the chip will shut down when the load is about 4A?

Resolved! Why did i get an Forbidden respond, when i try to open then site IHM001 Data Brief or the IHM001 Product Specifications:

Resolved! L6234 bootstrap capacitor 220 nF

Should the 220nF bootstrap capacitor connected to ground or Vs? The circuit diagramm and the datasheet are describing it differently. Both can be found here: https://www.st.com/en/motor-drivers/l6234.htmlThank you.
