Enable VIPER26K
Hi there,My question is if there is a way to enable or disable the Viper26K with for example an optocoupler.In the isolated flyback topology this is done cycle by cycle. But we want to enable/disable it in the high voltage buck configuration. Can we ...
Resolved! E-L9823 pin 21 - NC
Hi. Looking to use E-L9823 as a replacement in a legacy design.The datasheet states pin 21 is not connected. Looking to confirm it is a true "no connect" internally on the part. On our existing PCB it will be tied to +24V. Thanks.
Resolved! Heat output of RLimit of STEF01FTR (eFuse)
If the resistance value of RLimit is set to 14Ω to 22Ω, how do you calculate the heat generation of the resistor?Is 0.1W OK for other resistors?Also, can you provide the BOM for the evaluation board (STEVAL-EFUSE01)?
[vnf1048f] K Value
I'm using the vnf1048f chipset.k value is required for current sensing, but it is not specified in the data sheet.Can you tell me what the k value is?
ESD Rattings for SCTW100N65G2AG
Hello, I am trying to find the ESD ratings for this SCTW100N65G2AG. Usually its given in datasheet where its talking mostly about electrical stress data showing the ESD HBM and ESD CDM, but I can't find this information in this MOSFET's data sheet...
Resolved! STEVAL-WBC86TX -> Bricked accidentally, any chance of recovery?
Hello, So I recently received the dev board STEVAL-WBC86TX and was quite impressed with the features. Accidentally the wrong config ID was written to the board. Now I cannot connect to it again using the Windows utility. The USB to I2C appears to be ...
Resolved! DeadTime on ELVSTDRIVEG611
Hi , I've a question regarding the EVB in the subject , in the Data brief the Deadtime , with the pot in the center , is about 700ns , that seems to me a lot for the GaN device used .In the previous version ( EVSTDRIVEG60015 ) it was 100ns with the ...
Overvoltage fault while driving A2212 13T motor with Sensorless FOC
I am driving an A2212 13T motor with sensorless FOC with B-G431B-ESC1.The motor ran up to a certain speed.Then it stopped showing an overvoltage fault in the ST motor pilot.I am tried tuning Startup parameters.But the problem exists.Give me solution ...
Help finding a datasheet
Hey all,I'm trying to locate the datasheet of the following device:I think that it is a Zener, but I am not 100% sure.I've done the usual "Google" for the text, but I can't seem to find it.Thanks in advance.
L99BM114 - Advice on Battery Monitoring for 4S LiFePO4 with Open-Wire Detection and Removable Cells
Hi,I’m seeking advice on selecting the appropriate battery monitoring IC for a project involving a 4S LiFePO4 battery pack. My key requirements are:Accurate Cell Voltage Monitoring: I need to measure individual cell voltages in a series-connected pac...
