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

L9823 - Output not working when connected to Fan ( Random behavior)
Hello team, I'm using this L9823 for driving a 24v, 0.24A DC motor, but sometimes when i try to turn on the Fan it is not working and after some 3rd attempt it is turning on. The output is capable of driving upto 2A right. I monitored the current and...
Enable VIPER26K
Hi there,My question is if there is a way to enable or disable the Viper26K with for example an optocoupler.In the isolated flyback topology this is done cycle by cycle. But we want to enable/disable it in the high voltage buck configuration. Can we ...
