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!
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...

PowerStep01 application: Specify number of steps for RUN command ?
Hi,I have a question about the RUN command because there are different speed to MOVE command.In RUN command the speed min its 0,015 Step/second , in MOVE command the max speed min it is 15.25 Step/Second.I need run the motor at very low speed similar...
STCP202000CFP's Rth(j-c) definition
Now I start to use STPS202000CFP and try to estimate junction temperature. Then in datasheet, ST defines Rth(j-c). Question1 : where is "c(case?)" point in this discrete device, center of case?. Question 2: Does Onsemi have Rth(j-a) for this device ?
