Hello,I am trying to send first command from the MCU (s32k312 -NXP).I am able to send but I am getting SPI response likeAnd afterwards, no matter which SPI commands send, it always sends same response from the chip i.e. 0x610000As per the Datasheet, ...
Hi everyone,Good day!I'm currently working on modifying the Responder ID using CAN FD communication.I initially had a firmware running on an MCU that was capable of modifying the Responder ID. My goal now is to analyze the CAN FD communication from t...
Hi ST,I am using the STW3N170 in a linear application (constant current source) where the voltage can be 1500V and current as high as 16mA - total 24W.Can you please share the DC Curve of the SOA, please include in the graph the Thermal Instability d...
Hi! I'm using the STP16CPC26 as an LED driver, but have a problem where all the attached LEDs initially flash when powering up. This is a problem since this is a UI with a large-ish number of LEDs and you get hit right in the face with the bright fla...
We have approximately fifty modules in the field that use the L6981CDR. The schematic below shows how they are connected. The L6981CDR is used (in combination with other components) to generate an output voltage of 5V. This output voltage is used to ...
Hi ,Recenlty I designed the my custom board with LDL112PV33R . My Vin is from Battery charger BQ25620 which is 3.7V. Now LDO giving directly 3.7V at Vout. I done following diagostics. check marking on IC which ic ''L112 33''. which is indicating Fix ...
We're using this controller in our project and have the VCC pin tied to VBUS so the device does not pull power from the battery when USB is not connected (it was pulling ~125uA which is too much for our battery life as the main power is not turned of...
There are already a few posts which show there is an issue with getting the STSW-WPSTUDIO GUI downloaded. I replied to one, but I have yet to receive a response. I am looking to select capacitors to tune an RX coil connected to a STWLC38JR controller...
HelloCurrently, all information on WBC86TX and WLC38RX has disappeared from the ST homepage.Does this mean that the two chips are discontinued?I would like to know whether they should not be applied to new designs,and how long they are planned to be ...
Hello,I designed a circuit, but there is a problem with it. My supercapacitor (C5) is charging very slowly. I am using Dracula's standard OPV. It receives an average of 500 lux. It is charging so slowly that it is almost not charging at all. What cou...
