Hi. I have problem with connect to NUCLEO-WL55JC nucleo via ST-Link Utility. I am unable to connect with any option (hot plug, connect under reset etc.) or hardware reset to STM32WL55 MCU on board (there is some demo soft which is unable to erase). ...

Posted on October 11, 2015 at 16:32Hi. I have one question about AN4076 ''Two or three shunt resistor based current sensing circuit design in 3-phase inverters''. On the page 6, 10 we can see signals on shunt resistor. How it is possible it's bipola...

Posted on August 02, 2015 at 09:56Hello. Program flashed with ST-LINK and Keil uVision 5.1 without any errors. The problem is program start only after several resets. Anyone had similar problem? Thanks for any advice.

I want to know if TDA7297 can operate with junction temperature -40 to 150 degree of Celsius.If yes what is the purpose of giving max. temperature operation for 0 to 70 degree. I think it is some kind of bug/wrong definition used in this datasheet an...

So I am not sure it is clear: "If one of these conditions is violated, the function is not guaranteed and the responsibility is on your side."E.g. let's take two theoretical cases: 1) Operating/ambient temperature (Top): 0 deg. Junction temperature: ...

I would ask for definition (referring to a datasheet) of Top (operating temperature). It is identical as ambient temperature?

I am still not understand it. If operating temperatur (0 - 70 st.) is max why thermal overload protection is set to 150 st? Also why min. operating temp. is 0 if junction temperature (which is also referring to working IC by definition) is -40? Espec...

TDA7297 - temperature. According to datasheet "Top operating temperature" of TDA7297 is in range "0 - 70 st.C". However junction temperature is "-40 to 150 st.C". So it is possible for this amplifier to work in -40 temp. environment?

NUCLEO-WL55JC cannot connect to target.
