I have following three concerns related to SPI interface timing of L9825 low side driver IC. Please refer the image below. 1. Do we really need to toggle the clock signal within 100ns after NCS changed from High to low. If this 100ns is exceeded what...
I get an error message when I try to connect with the STEVAL-WLC38RX evaluation board using STSW-WPSTUDIO. I am using v2.7.2 of WP Studio. See error message attached.
Hello, I want to buy STEVAL-WLC38RX product..I can't sell it online.. may I know where I can buy it?
I want to use the PM8805 as POE controller in a custom project for a 25W classified POE device. The PM8805 should generate the input power for 2 boards in this device.However, when connecting only one board with approx. 30uF input capacitance, the po...
Hello ST Community,I am currently developing a product using the PM8805 chip and have purchased and tested the STEVAL-POE001V1 evaluation board. Based on the reference design provided by ST, I created my own circuit diagram and manufactured a custom ...
I'm working on developing product, for that I was going through the documents of AC/DC & DC/DC products for reference but, I'm not able to find any detailed documents. If you have any application notes or design documents regarding these products, it...
Hi Sir, Does the STUSB1602 support Alternate Mode? Is an MCU required to enable it, or can it be implemented directly with the MCU alone? Is there any example code available? Thank you.
Hi the datasheet does not contain the thermal junction temperatures for the VFQFPN48, hence hard to work out the max thermal temps for the device. please can you supplyregardsRoss
Dear All,I have created a new schematic for a project I am working on, using the POE Dual Active Bridge PM8805.I have used the reference designs from the datasheet, as well as cross referencing other POE designs online.If someone has the time, I woul...
Hi All,To start, I'm a hobbyist and although I am OK with digital, analogue and the maths surrounding design is beyond me. I am seeking assistance in specifying the values and component suggestions for the CM Filter as noted in figure 7, page 19 o...
