When measuring my VIPER267K flyback power supply, I noticed that the frequency and duty cycle of its VDS waveform kept jittering. Is this normal? What could be causing this? 
Hello all, this post just to know if the L9788 Automotive Engine Management System IC can be interfaced to a microcontroller via SPI instead of MSC bus (single ended interface instead of differential one).Thanks a lot,Regards.AC.
Hello,STPSC10H12G-TR is used in our projects, it's NRND and may be going to EOL.Do you have recommended replacement for this part? Thanks!
Hello,I'm currently evaluating STEVAL-ISV020V1 using AN4397 and I'm not reading any voltages from both LDO outputs.Here's my setup:PV_in: 2.6-2.7 V PVBATT: 5v supercapSW1 and SW2 enabledI can confirm that the supercap is charging as STORE shows ~3.9-...
Hello Engs, How do you calculate the mission profile for the LDO40LPU33RY LDO regulator in an automotive application? Best regards
I am testing the board with a 14s Li-ion battery, but I am unable to read the cell voltages or configure any register through the GUI. I shorted the X1 and P2 power supply inputs and supplied 12 V to both. This was the only setup in which I could get...
We are currently using the L9305 IC to drive solenoid contactors in our project. The hardware configuration follows the specifications provided in the datasheet.We are able to communicate with the device via SPI and read all registers. However, we ar...
Hi,Below is the setup I'm using. An SPV1040 connected to a small 2Vmp solar panel charges two 50F supercapacitors connected in series up to Vout = 4.8V. The design is taken from the AN3319 application note of the STEVAL-ISV006V2. Currently, I have ma...
