STPM32 example, about energy factor in metrology library

hello.If you look at lines 343~352 of the metrology.c file in the document STSW-STPM002 of STPM32, it is written that you do not need to calculate the "energy factor" if you have calculated the "power factor".And define FACTOR_POWER_ON_ENERGY to 858....

How does the PM8805 behave if it is designed into a PD device that is connected to a Passive PoE Power Injector? Thanks, Fintan

IS there any evaluation board or reference design available for "STGIK50CH65T" IPM

My requirement is to run BLDC motor using Hall sensor feedback. Electrical requirement is 300V DC, 10Arms. I have selected "STGIK50CH65T" IPM for my requirements. Please propose a reference design or eval board or suggest different part if i am wron...

Need to know the top marking of KF50BDT-TR ,LF50CDT-TR

RHFL7913A, Power-Up

Hello, we are using the RHFL7913A to provide a negative supply for operational amplifiers. When we first supply the positive voltage to the op-amps, there is a positive voltage at the output of the RHFL7913A that is clamped to 0.4V by a protection di...

High voltage conversion (1000V to 25V) for low power application - Are there some application circuit close to those values?

Hi, For a project I'm working on, I need to design a 3.3V power source (to power a microcontroller and measure circuit), the max load should be about 100mW. I only have a voltage source around 1000V next to it and I have to use it to make the 3.3V vo...

What is the maximum supported speed for stepal-spin3204?

We are going to rotate the BLDC motor at a speed of 200,000 RPM.Is step-spin3204 possible?
