STEVAL-PCC009V2 + EVAL6480H with cSpin and minimum wait time between sending the cSPIN_Set_Param() command (IAR C/C++ IDE)
Dear all,after some time I'll be able to correctly run the demo applications that came with the cSpin firmware libraries (search about STSW-SPIN005 on the ST site).The first part of this post is about how to set the demo design and compile it, the la...
ViPER16HN non-iso buck failing after one to four weeks of operation at 277VAC. Could the pulsating input voltage be the problem?
Dear AC-DC Forum, I'm helping to troubleshoot a design using the ViPER16HN as a non-isolated buck. It's part of a power supply that uses PFC, so the input voltage goes from nearly zero to about 400V peak each AC line half-cycle. When used at 277V...
STEVAL-ISB042V1 in Tx mode
Posted on February 28, 2018 at 09:31Hello,Where could I find the binary file STWLC33_TxMode_RAM_binary.bin need for set the STEVAL-ISB042V1 board in transmitter mode ?The STEVAL-ISB042V1 development board is a dual mode wireless power evaulation boa...
FIT Rate/ MTBF of ST1L08SPUR
I'm using ST1L08SPUR in my project. For reliability analysis I wanted to know FIT rate/MTBF of ST1L08SPUR.Please help me out in this concern.RegardsNidhi P Shetty
STGAP2D isolated half-bridge gate driver: very specific question related to on-chip internal voltages applied to the gate of GOFF NMOS transistors with respect to GNDISO_A/B and their current drain versus gate voltage (internal) characteristic
The reason I need this information is because I would like to use the two internal 'half-bridge' of the STGAP2D gate driver for directly driving a resistive load at ~ 300 mA (more explanation below). In addition, the configuration / topology I am tar...
It is a question of regulator RHFL 4913.
It is a question of regulator RHFL 4913.There is a noise graph on the data sheet(DocID10005 Rev17 Figure 37), but there is a peak at 30 kHz.Is RHFL 4913 a switching power supply?If it is not a switching power supply what is the noise of 30 kHz?Thank...
STSPIN250's can I use 3.3V for it's logic pins?
STSPIN250's EN\FAULT and STBY\RESET pins are described as "Logic input 5 V compliant". Does it mean it only supports 5V logic or 3.3V logic will do the job of bringing these pins high?Want to use this device with STM32L496 MCU which is a 3.3 device.
STEVAL-PCC009V2 missing source file for IBUU source code, where to find it? Many trouble with this board and no answer...
Dear all,as stated inside the UM0935, page 8/53, §2.2 it should be on the package also:"The IBU UI tool includes the following items:�? Hardware content:– One board– BOM list– Schematic�? Software content:– DFU firmware– DLL files of the I2C, SPI and...
