External battery STM32 power shield

Hi, I want to ask a question. I have STM32 power monitor shield and is it possible to measure current without powering the device by the shield? I want to use battery to power the device and measure the current drown from battery.

Is anybody can tell about connection of EVALSTPM33 with 2 current channels(with shunt as well as CT)

the schematic for STPM33 is atttached.

for L9826 chip when apply 13v and "output shorted to Vbat" is detected , when remove this fault the output remain pulled high , so is there is any steps needed to be applied to recover from this failture ?

STEVAL-IPMNG3Q : purpose of EM_STOP signal

When connected to te STM32303E-EVAL board the EM_STOP will be connected to either PB7 or PE15 of the MCU.In my humble opinion the EM_STOP should be connected to the TIM1 BRK function , but neither of these pins can provide the correct functionality.A...

Suggest MOSFET for motor control application using VNH3SP30

I want to control a motor using VNH3SP30 driver IC. For that, application schematic is given in PDF(19th page) given in below link (from ST microelectronics website).https://www.st.com/resource/en/datasheet/vnh3sp30-e.pdfHere I want to get the sugges...

I am using L6699 ic for 250W DC-DC Converter. Sometimes I am getting strange voltage waveform across the resonant capacitor of my LLC circuit. I want to understand what is the root cause for this behaviour.

I am attaching the voltage waveform across resonant capacitor of 30nF.
