BTA16 and ACST10 which is better AC switch for AC Phase cut application?

Hello,We want to design best AC Phase-cut circuit. we have design BTA16 based AC Phase-cut but flickering issue occurred often and also design new AC Phase-Cut circuit with ACST10 which work fine.My query is that which is best AC switch BTA16 or ACST...

¿How to identify authentic TRIAC (BTA41)?

Found a seller whom offers BTA41-600B power TRIAC at lower price than expected, altho they asure those are authentic ​ST semiconductors, i can't permit unexpected behivor from this component for my application. ¿How could I ensure it comes indeed fro...

PM8804 Design Help

I'm looking to use a PM8804 along with PM8805 to produce a 24V, 2.5A POE PD. Are there any application notes available on how to design and calculate components for a forward active clamp converter similar to the schematic in the datasheet. I've look...

I tried to run ihm08m1 using 6 step algorithm , on BLDC Sensorless Motor with Nucleo F401RE Board but motor did not run? I made all arrangements as asked in the datasheet. Please share your valuable views.

Which is the best suitable isolated flyback controller for the input upto 1KVDC and output of 20W ?

I am designing a Isolated Flyback SMPS with input range upto 1KV and output of 20W. I couldn't found any flyback controller which will support this range. I found one offline PWM controller named STCH03 which is having limited 650V start-up.So is it ...

we use your STC3115IJT and your STC3115IAJT. we initialize the STC3115IJT and request the device ID, we got ID = 0x14 we initialize the STC3115IAJT and request the device ID, we got a different ID from 0x14. Isn't the Id have to be the same !?

We expect to got the same ID cause the devices is the same and the only difference is the battery voltages.

powerSTEP01 package (VFQFPN 11x14x1.0 mm) thermal resistance

For documentation purposes i need to estimate the worst case temperature for the powerSTEP01 that occurs in our application. I already calculated the worst case power dissipation so i am able to determine the temperature with information about the "j...

STM32G071 Can't read ADC Measurements through IN15

Hello CommunityRecently I'm in a project with the NUCLEO-G071RB.I been working with ST boards for a long time but this time, i cant make measurements through specific channel "ADC_IN15". Pin PB11I made other channels to work ( IN0, IN1 etc...) but w...

We have been using the L6219 motor controller for meany years (sense 2002) and are wondering if there is a improved part with short detection and a more robust output stage available that has similar features ?

STSPIN32F0 [Increasing maximum sink/source current capabilities]

Hello,The 600mA current available on STSPIN32F0's gate drivers seems too low for high current applications.Does ST or anyone, could suggest any 'buffer' to increase that current?Thank you!
