L9305 SPI example

Hello There, Where can I find the example code for interfacing L9305 through SPI? Please suggest some sample Code.

Hi,I am designing 2.7kw boost converter for which I am using SCTW100N65G2AG MOSFET. In the datasheet it lacks information about switching times(like rise time fall time and delays) and max DV/DT the MOSFET can take before failing. I feel these data i...

A5975D Blow on Power Up

Hello, I am using the A5975 in an applicaiton that blows on power up. This sounds similar to the issue in the post below:https://community.st.com/t5/power-management/st1s41-step-down-switching-regulator-destroys-itself-on-low/m-p/171683 I have been u...

L9305 External fail safe switch mandatory and usage in parallel

Hi,I was studying your product L9305 in order to drive proportional valves and it was not clear to me if was possible to use it without the external fail safe switch. Is there a way to bypass it and not mount it?Moreover, if I want to use the 4 chann...

VNF1048F Reverse current behavior

Hello,I am planning to use the VNF1048F as a eFuse for my current project.From the datasheet it is not clear to me which is the behavior of the VNF1048F in case of reverse current.Does it automatically close the MOSFETs (to avoid diode conduction), d...

STUSB4700 application without I2C conifuration

What happens if I use STUSB4700 in my application but I do not communicate with the STUSB4700 over I2C? Will the STUSB4700 negotiate a contract as a source with the sinking device and offer the PS FB voltages which are connected to the GPIO? I would ...

dynamic resistance of TVS

Dear Sirs, Could you advise me dynamic resistance(Rd) of TVS such as SM6T33CAY used to clamp against pulse 5B per ISO 7637-2 or load dump B in ISO 16750-2. Its voltage source waveform is clamped instead of exponential surge curve. Thanks John

Broadcast init message,Broadcast frame structure for l99ldlh32.

where can I get example code for SPC58EC80E3. I am trying to give multidevice broadcast command but not working. Attached note for ref. Wether Broadcast init message are correct. Single device messages are as below in network. 0x200x240x140x100x...

Resolved! VN9D5D20FN frequently setting SPI error bit in global status byte, datasheet not clear on cause

I am controlling a VN9D5D20FN high side driver with the SPI2 interface on an STM32F373. I can communicate with the high side driver, and sometimes briefly get an output to turn on using SPI control. However, frequently the high side driver sets the...

Please help me understand strange VN7050AS behaviour

At about 6.3A load the VN7050 switches off the output, which is much lower than I expected given the limit ratings in the datasheet, I suspect my thermal via's are not sufficient and that it is reaching an overtemperature condition, so have made chan...
