Hi,As the title described, how to mitigate the current behavior when stm32 is applied power? My commercial power system are quite sensitive when MCU is power on.For example, let stm32 enters into low power mode once power is on and then control the c...

Hi,I'm using stm32f103vet6 in my design, but due to the limit power budget, the MCU consumes much power(60mA per MCU , while I used 2 chips in my design), result in frequently triggering over current protection. Is there pin to pin compatible STM32L ...

Thanks for your quick feedback.Yes, it has current sensor built in power module, but it didn't say how I can read the current value it measured.All I saw is the customized board designed by ourself easily triggered its over current protection. Anothe...

Actually there is no information to guide me to measure current on power module.(we do not have the schematic or PCB)But it is possible to measure current on customized cards by ourselves, while we need to cut the PCB trace off and add shunt resistor...

Hi Danish1,I have to say I'm testing the hardware system but without enough hardware detail design information of the power system and power module(no schematic, only user manual). I tried to contact the technical support from manufacturer but failed...

Hi Andrew,No , it is a independent power module for uTCA system, product weblink: https://nateurope.com/product/nat-pm-dc48/There is big chassis to hold power module and customized cards. We used STM32F103VET6 as microcontroller on customized cards. ...

Hi Andrew,Thanks for the suggestion. Current measurement with current probe is an option, but we do not have it now, placing order for it takes us 10 days more.Monitoring the current using a simple shunt needs PCB routing damage in our design, it's t...
