L6562 : Need to understand the functionality of the PFC IC

Hello everyone,I have made the L6562 ref circuit (for 250W provided in the datasheet) on general purpose PCB.I have discussed with coilcraft members, they have said, for initial conditions the resistor divider from rectified mains input will provide ...

Having trouble starting your motor?, watch this https://youtu.be/As6cLKZzHyA It clearly explains what the startup process is.

stm32g431

on stm32g431 cannt used 2 current sensor isolated how can resolved this problem ?how can tel to motor control team for add this one on library ?

Where can I find an LTSpice or PSpice model for L6591 IC?

When we apply or connect load to Viper26. The output is being dropped from 12 V to 2 V. With current being continuously fluctuating. How do i solve this issue ?

We have designed the board for,Input:Voltage - 200 to 240 VFrequency - 50 HzOutput: Voltage - 12 V Ampere - 400 mA (*Considereing the datasheet, the default float design has been approached. Without the use of any Current Limiting resistor)But unfort...

To limit the OCP of an L6599AD to one function

Hello. I have a question about the okp function while using l6599AD. The daasheet states that the ISEN pin operates in the hiccup mode when the voltage is 0.8V and the shutdown when the voltage is 1.5V. When testing with a regular electronic load, th...

Hall effect sensor noise

My motor works fine at the first 10 to 20 sec. However, I observed there is some noise spike and the speed feedback error occurs. What would be the problem? I have added 3300pF at the output of hall effect sensor.

Hi, I am now driving a 20 pole motor with 120 degree hall sensors. However, I do not know how to find the electrical placement angle. This is the output of the motor phase response and hall effect sensor response. Thank You.

I realized a driver for 35W 48V @ LEDs based on the integrated HVLED001A with regulation on the output of constant current type (second sisde) that uses the integrated TSM1012.

I have problems in setting up the regulation loop using an optocoupler, can you tell me how to contact your field application, possibly speaking Italian?Thanks for collaboration
