Resolved! Expected EOL of L9822E and L9823
Hi everyone, I am looking for s low-side driver that will last more than 5 years, preferably 10. For functionality, L9822E and L9823 are good candidates, and I would like to know their expected EOL. Thanks Insu
Custom WPT RX based on STWLC98JR
Hello!I am new to circuit design so please treat me patiently :relieved_face:I am building a receiver circuit based on STWLC98 and following the design guides from STEVAL-WLC98RX wireless power receiver evaluation board manual. My question is what to...
Resolved! How to drive the L9823 (SPI) via 3.3V MCU?
Posted on March 27, 2017 at 18:51 I'm using STM32F303 which operates on 3.3V how can I communicate with the L9823 SPI which runs via 5V? thank you
L9823 - Output not working when connected to Fan ( Random behavior)
Hello team, I'm using this L9823 for driving a 24v, 0.24A DC motor, but sometimes when i try to turn on the Fan it is not working and after some 3rd attempt it is turning on. The output is capable of driving upto 2A right. I monitored the current and...
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 ...
