how to control SCR connected back to back using MOC triac ic?

i want to make ac voltage controller using two high power SCR connected in back to back.using pulse transformer to trigger SCR it works fine.but how can we control using MOC3052 OPTO TRIAC IC circuit diagram ?LOAD is highly inductive like induction h...

STNS01 led blinking in end of charge

Hello, I have already produced more than 6000 electronic boards with the STNS01 component, no problem.Today a problem appears with the STNS01 component: The battery recharging happens normally, but once the battery is charged, at 4.2V the STNS01 comp...

STWLC33 NVRAM update

Hi,we're using STWLC33JRF in our design and recently we discover that we need to change some configurations trough the NVRAM. We've tried using ISB043v1 dongle to update the NVRAM but it won't detect the chip.We've also tried to write our own I2C dri...

Can anyone provide me the Formula to Choose Diode rating of Center Tapped Rectifier with LC filter?

Current rating per channel of VNQ5050AK-E?

Can I know what is the max current rating per channel of the smart FET VNQ5050AK-E, it is quad channel IC and its total current is internally limited to 19A.

I am using eval STPM34 for energy meter project. I am connecting ESP32 to STPM34 using UART. i.e. only Tx and Rx are used. I am writing ESP32 code using Arduino IDE. I cannot read any other register data

I am using eval STPM34 for energy meter project. I am connecting ESP32 to STPM34 using UART. i.e. only Tx and Rx are used.I am writing ESP32 code using Arduino IDE.When I use Serial2.read() function to read any register data, I always get "160 0 0 4"...

What can increase LM7915 ADJ-Pin current increase during start up?

During start up of a very simple LM7915 LDO within a split supply system for +/-15V sometimes ADJ-Pin Current increases during start up phase above the usal level.When this occurs, LM7915 can hang at 0V output voltage.As soon as adj pin current retur...

Hi, I'm wondering how to use self-commissioning SCC_GetRs(CSCC this) function from FOC Motor Control Library, I've used it but the returned value is always 0.

Step-by-step tutorial with example of calculations of the PFC integrated in the STCMB1

Greetings All,I would like a good example of calculations of the PFC intergarted into the STCMB1.So far, knowledge has been acquired about the LLC resonant. But not the PFC.Which chip is the closest ?Thank you.Best regardsSerge
