Request of sample
Dear STM,I need VNQ5050AK-E 31pcs of sample.Could you check that you can supply sample ?For this, I called sales office in my area but they didn't answer.If you can't supply sample for free, I want to purchase them.I need them urgently.(I want to r...
Need help with erroneous period readings on the STPM34.
Hi, I have the STPM34 chip connected to a 60Hz line continuously for days and it reads the frequency correctly almost all the time. However, there are instances where it would report back ~37Hz instead of 60Hz a few times in a day or sometimes it wou...

IC STPM33 is possible to use for measurement: active power, apparent power, RMS value of current and RMS value of voltage. The question: does it measure the RMS value of current in the case, when AC current is not sinusoidal.
The voltage is sinusoidal but the current is after PWM modulation ( dimming of LED lamp)
Is the use of Reset and Alert Pins mandatory on STUSB4500BJR?
We are planning to use the STUSB4500BJR (WLCSP-25 package).Since we want to avoid using micro-vias, we will not be able to fanout the inner 9 balls of the package.This would afffect the following signals:Pin B4 - CC1DB (not used, can be connected to ...
