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

Alternative for TIP31C in SMD Package

Dear Experts,now working for vehicle ignition control through Relay (https://www.conrad.com/p/tianbo-electronics-trv4-l-12v-z-automotive-relay-12-vdc-1-change-over-1366523) , i have attached my circuit and i want to replace the tip31 to any other SM...

We make wireless battery charger using STWBC-EP. Without putting any receiver, after sometime Red LED blinked continuous and GUI indicate QFOD error. So we need your guidance to solve this problem.

Why is not available any more AN2544 ? (and many other Application notes of VIPERx2)

Why ST silently removed AN2544, AN1357 and many other Application notes of VIPERx2 ?:(

B-G431B-ESC1 - Fine shaft position control

Hi,In my application, I'd like to control the position of the motor shaft instead of the speed, since I have more than one motor and I want them to move in phase (they are connected and controlled by CAN). I saw this board has the possibility to add ...

What is this method of driving BLDC?

Hey guys. We are trying to drive a 350 watt scooter sensored bldc motor.we use common circuits available online and we use gate drivers(ir2103) with 6 n channel mosfets to swith between phases.In every step we pull one phase high and one low and the ...
