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?
Driver IC VNLD5300TR-E _Delay time if Current trip happened
IC Part Number _ VNLD5300TR-E Hi Team, we are using the above IC in our design. If a short circuit occurs and the current exceeds 2 A, how long will it take time for the IC to shut down? Thanks +918882226127
Clarification on VN9E30FTR Current Limit Specifications
I need some clarifications regarding the IC from STMicroelectronics: VN9E30FTR – 6-channel high-side driver with 24-bit SPI interface for traffic signal controller applications. In the datasheet, it is mentioned that the internally limited current i...
Resolved! Datasheet by diode
Could someone tell me what type of diode I have? I can't find any data.L X GP128I appreciate your help.
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...
Resolved! 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 ?
HVLED007 in PSR
Hi,I am using HVLED007 in my 80V, 45W SMPS (Input voltage range 160V-300V). Is it possible for the IC to operate in primary side regulation mode instead of the conventional opto-coupler-based secondary side control? Unlike other ICs, I cannot see an ...
