Resolved! LED7708 Random LED switch off issue with driver
Our requirement was to create a LED driver circuit to power 12 strings of 7 LEDs from a 12V DC supply with a nominal current of 20mA per string.Using the STEVAL-ILL035V1 Development board data for PCB layout guidance and the LED7708 design tool sprea...
Resolved! Looking for an L9963E C STM32 Library
Hi everyone,I'm currently working on a project where I need to interface an STM32 with the L9963E BMS IC from ST. Before developing my own driver, I wanted to check if anyone has already written a C library for this IC and would be willing to share i...
BMS63EN connection problem
BMS63EN connection problemI connected AEK-COM-ISOSPI1 and BMS63EN through PinMap provided by SPC5.However, I found two problems.1. When the input voltage is 56V, when I measured the voltage of Cell0, the voltage was measured as 10V~12V, and the volta...
powerStep01: implementing hardstop
Dear Madam/Sir,We are using powerStep01 and must implement motor "hardstop" purely in hardware (no software intervention).We consider these options:- using the external switch SW and bit SW-MODE = 0;- OR, with all voltages externally supplied, cut of...
LED1202 Can we use over 5V for VLED?
Hello,LED1202 Can we use over 5V for VLED?For example, We plan to use 5V power supply. It's maximum voltage is 5.25V.It is my understanding that we can use maximum VLED voltage is VCS_MAX plus VF of used LED.Is that right?Thanks,
Resolved! L99615C current measuring problem
Hello,I am having trouble measuring current with the L99615C STEVAL kit and wanted to check if I might be doing something wrong. My jumper settings are as follows: J19, J20, J13, and J14 are shorted, while J15, J16, J17, and J18 are set to position 1...
Resolved! L99615 demo GUI CRC
Hello,I’m encountering an issue where I’m unable to fully understand the behavior of the GUI in relation to the commands being transmitted via serial USB to the NUCLEO. I’ve figured out that there is a CRC at the end of the raw data being transmitted...
issues with a TD352
Hi Everybody,In the case of a LEDs tubes dimmer, I'm using a TD352.It works very well. But in some case (and for the moment, I don't know why), my IGBT and the resistor wich controls the gate of the IGBT burn.I just replace these two components and a...
Resolved! Expected EOL of L9822E and L9823
Hi everyone, I am looking for s low-side driver that will last more than 5 years, preferably 10. For functionality, L9822E and L9823 are good candidates, and I would like to know their expected EOL. Thanks Insu
Custom WPT RX based on STWLC98JR
Hello!I am new to circuit design so please treat me patiently :relieved_face:I am building a receiver circuit based on STWLC98 and following the design guides from STEVAL-WLC98RX wireless power receiver evaluation board manual. My question is what to...
