Hi everyone,
I'm going to drive a low side mosfet with a PWM signal with variable duty-cycle in the range 10%-100% but I see the duty-cycle is variable only in the range 99%-50% (see the video below).
The frequency is 100Hz and the mosfet driver is an PNP so the pin PC9 (net PWM_1) of the...
Hi,
we're designing a battery management system that uses TI-BQ796xx family of AFE/transceiver.
The different boards or modules/ICs communicates between them by using a differential bus in daisy-chain mode. The interface is based on a transformer with a cetral tap as follow:
I found two...
Solved!
Despite, from the block diagram, the MDIO control block seems to be a stand-alone part of the IC, to work properly, it is mandatory to provide the 50MHz ext clock to the IC.
The power-up timing figure 2 highlight the presence of the external clock in the inital phase.
Hi everyone,
I've designed an embedded board with a SOM module based on STM32MP153 microcontroller and a PHY transceiver from ADI, the ADIN1200. The connections between the two devices are the followings (from AN5031 - STM):
I've some issues when I try to communicate with the PHY ADIN 1200...
Thank you FvM,
I was looking for this table from time.
So, as you suggest the only way is to use conformal coating. According to the IEC 62368-1 I have to consider the table G13 and, if the voltage is >455Vpeak, I need to perform some test (G13.6 of IEC 62368-1) on the coating.
Is it correct?
Hi FvM,
thanks for the reply.
Probably I exposed my doubt with the wrong words...I wan't costruct cases where slot are not useful. I just want to undertand which are the cases where the slot could help and which are the cases where the slot is unuseful.
However with your response:
you give me...
My doubt is not about the specific application shown in the image but is a general doubt/observation. The table is just an example to show the difference between the second column (the one that grouped all the material groups and the other column on the right that make differences between...
Hi everyone,
I've a doubt about the benefits of the air gap to increase the creepage distance between two conductive parts of a component.
I could explain my doubt by using an example with an ethernet transformer.
As highligted in the previous image, I suspect it is possible to consider 2...
Hi everyone,
what is the correct method to view all the selected components in the schematic editor?
I can select the interested component by using the "Find similar object" function as by using the "SCH filter", however in the sch list panel I cannot view all the selected objects from the same...
Hi everyone,
I'm going to implement an ethernet connection to my electronic board. The board will use an "automotive-style" connector like the SUPERSEAL from TE.
I'm thinking to use 4pins (+ 1 pin for shield) of the Superseal connector to transmit the ethernet signals from the board to the...
Hi everyone,
I'm going to design a PCB with working voltages up to 1000V and I'm following IEC 60950 standard where the creepage/clearance distances are related to certain pollution level.
The system will work in an industrial environment thus pollution level 3 will apply.
In order to reduce...
Hi everyone,
I'm designing a hierarchiacal schematic by using multi-channel design.
I create 2 different channel created by placing 2 Sheet Symbols (let's say "SheetA" and "SheetB"), that both reference the same schematic, "Schematich.SchDoc".
When i compile the project, the nets on "SheetA"...
