Power management

I should know the FIT / MTBF of ST1813MWX7F for reliability calculation. Where can I find this information?

How to choose resistor and capacitor for a snubber circuit used in a triac controlled with an opto-triac

Hello, I want to design this kind of circuit using a Vline of 600V: I would need to use Triac model T2550-12T. For the R1, R2, R3 and C1, I know what are the values, but I was wondering what is the power of the resistors and the capacitors that I nee...

Hello I intend to incorporate MASTERGAN1 switching at 1.000MHz with duty cycle control How well MASTERGAN1 behave at 1MHz?

HelloI intend to incorporate MASTERGAN1as a resonance converter switching at 1.000MHz with duty cycle control from 20% to 50% [ symmetrical]HV <=40VDC Output power up to 40WattsHow well the MASTERGAN1 behave at 1MHz?Compared with TI LMG5200?Thanks

High-Side Switch VN9004AJTR circuit and program design

High-Side Switch VN9004AJTR is fairly new, so nothing on the web to help with circuit and program design. It has a simple default circuit and MCU programming configuration, but it has some nice features that require more complex programming. Has any...

VIPER16LN thermal shutdown happening in 2mnts at 3.75W

Hi Team, we are using VIPER16LN in one of our project. we are facing thermal shut down happening within 2mnts time. the below are the testing conditionInput voltage: 230VACOutput Voltage : 15VOutput current: 250mABut viper16LN can handle around 6W po...

Manual rotation of the stepper motor shaft to start the PowerSTEP01 controller.

I wonder if it is possible without external sensors by manually rotating the stepper motor shaft to initiate the PowerSTEP01 controller. Manual rotation of the shaft triggers the controller while informing it of the motor's direction of operation. Af...

having trouble getting the motor to run at a consistent speed

I am working on a project that involves controlling a DC motor using a microcontroller. I am having trouble getting the motor to run at a consistent speed and it keeps stalling. I have tried adjusting the PWM signal and playing with the circuit but n...

What are the versions of STUSB4500?

Hello,While having a look at NVM flashing example, I came across those lines:I2C_Read_USB_PD(0,DEVICE_ID,&Buffer,1); // DEV_CUT 0 : 1600 , 1 Reserved , 2 : 1602 , 3 Autorun   if(Buffer & ID_Reg >= CUT) { if ( nvm_flash(0) == 1)   prin...

Lack of documentation and inconsistency in STUSB4500Q code example

Hello,I'm implementing the sink side of a usb-c PD system based on STUSB4500Q.I had a look to documentation and to the example code.It looks that the code was written by a first year intern. The ~25 global variables,inconsistency in variable / consta...
