Ignition coil conduction and switching losses. Used in two wheeler ignition coil.
Hi,We are using IGBT STGD18N40LZ in Two wheeler Ignition coil Ignition coil is inductivePlease suggest, how to calculate switching losses theoretically and measure practically.It's Purpose is to calculate temperature rise in different condition.Pleas...
SPI excample for the L9026
Hello,ist there an SPI example available to control the L9026 for switching 8 solenoids?Or even an example how to define the HEX command i have to send via SPI especial only to switch all 8 channels on and off.
L9963E BMS front-end: SPI + isolated daisy-chain?
Hello,I am looking for an AFE for a BMS for a vehicle battery. An option would be part L9963E.The battery is 28 cells in series, hence two 14-channel AFEs would be necessary.The BMS is centralized, on one PCB. I would like to keep the communication s...
when i try to write to sector3 and sector4 of NVM registers of STUSB4500 sector3 registers are all set to 1 why that was happening?
when i try to write to NVM register sector4 alone it works fine but when i try to write to sector3 and sector4,by calling the two functions to write to sector3 and sector4 .sector3 registers are all set to 1
Part STM6904 Doc ID 14289 Rev 3 Pull-up on /rst output open-drain in Table 2. Signal names and functions on 8 RST Output Active-low open drain reset output (10 kΩ internal pull-up) I think the note (10 kΩ internal pull-up) was meant for pin 1
From the rest of datasheet and also from the test we have performed preparing a test circuit it looks like there is no pull-up on the output (as it should be for an open drain), if so please update the datasheet. Please confirm if we are right or oth...
Why does L7905cv have an output voltage of -10V instead of 5 when inputting -12V ?
I' m sure GND has been connected.
cascade clock feed of multi STPM3X chips?
Hi, I would ask a question about STPM3X, when I use multi chip of STPM3X, I can use One crystal and then cascade clock feed (Figure 27 in datasheet). Does this change the performance and the power consumption for the first master chip and slave chip?
Resolved! X-Nucleo-IHM08M1 3Sh and Nucleo-F746ZG use MotorControl Workbench 5.4.5 Over current
I use MotorControl Workbench 5.4.5 to control BLDC, but it always send error "over current". I check all setting but not have mistake in MotorControl.The warning displayed by MotorControl Workbench is due to over current with my settings, but the Ma...
Resolved! About Part#T2535-600G.
Could you please help check the normal range of resistance vaule between Pin A1 and Pin G ? Will it be higher than 72.5ohm? Or will the resistance vaule become higher due to some manufacturing process?
Resolved! How to write a working program to control a BLDC motor using STM32CubeIDE. X-Nucleo-IHM08M1, Nucle-f401RE
As I wrote above I just need to learn how to write a working program to control a BLDC motor using STM32CubeIDE. It's a general question, but I do not need more. I am trying to do it by myself for months, but I have no idea how to write my code corre...
