Power management

Hi How can I propose intellectual property (patent application) to your company? Area: Method and IC design for LED current balancing Thanks Oleksij Khyzhniak

STEVAL-POE001 not engaging when connected to 802.3AT PSE

I purchased a STEVAL-POE001 evaluation board for testing. Connected the board to several PSE units including an injector and a switch that supports 802.3AT. The board and the PSE LEDs flash momentarily but will not fully engage. I do not have any...

Port SPN3 motor-control examples to DK2?

We are considering using a combination of the stm32mp157 and several powerSTEP01 devices in a system with multiple stepper-motors.The X-NUCLEO-IHM03A1 plugs into the -DK2 just fine, but the SPN3 examples only work on the F0xx, F3xx, F4xx, and L0xx se...

Testing VN5010AK-E, need confirmation that I got the datasheet info right.

Hello to all,I found this new IC and want to test it for a while, but don't want to fry it before that :D, so just a several questions, where I doubt that I understood the datasheet correctly. There will be no uC, so I don't need current sensing, so...

Using the VNHD7012AY development board to run a brushed 12V motor, I have trouble at initial startup trouble that appears to be a problem with the fault circuitry.

Picture #2: (Current waveform) Operation with resistance added to OUT linePicture #1: (current waveform) Picture when motor does not start Regardless of what values I install for gate resistors (0, 475, 1100 ohm), Vref resistors (8-40K) adding ext fi...

Question about STPM01 not reading 0 at no current. (See details)

Hi!I have a couple of questions regarding the STPM01 energy metering circuit:We are using it for measuring currents only with Rogowski coils. (We have 4 circuits on our board).We are not using the voltage measuring, so it is not connected.The microco...

Max load on output of STEVAL-ISC005V1

Hello, What is the max load I can put on STEVAL-ISC005V1? I mean, I try to load 100W on PD03, setup to 20V/5A, with an electronic load but something burn on the evaluation board, I thing I make something wrong. Could somebody help me with this topic?

TD350E - interpreting date/batch codes and desaturation sensitivity

I'm presently debugging an intermittent desaturation issue in a stable product platform (stable as in 10+ thousand units over more than a decade).From what I can tell so far the TD350 device is signalling a desat on occasion without a reason I can ob...

The data sheet for the SCR BTW67-1000 is not clear as to which pin is the gate. The diagram shows a pin to be parallel to the centre line of the mounting holes but on the device there is no pin as such. Is the smaller pin with a smaller hole the gate? A
