Resolved! The frequency and duty cycle of the VDS waveform of VIPER267K are constantly jittering.
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? 
Resolved! Can L9788 be interfaced to a microcontroller via SPI?
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.

Resolved! L9963 Voltage measurement problem
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...
Need support related to L9305 valve driver bringup
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...
SPV1040T stays ON and passing voltage from output to input
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...
Resolved! ACST series
I would like to use the ACST series as an AC switch for a 90kHz AC capacitive load. Is this possible?
Clarification on VN9E30FTR Current Limit Specifications
