According to the reference circuit, R43 is 75kohm.Also UM2154 User manual said that R43 should be higher than 30kohm.What happens if R43 is 22kohm. Is overcurrent detected by STSPIN32F0?
HelloI need to estimate IFSM for certain current pulse.Does anyone know how to do it?I found this app note :Schottky diode avalanche performance in automotive applications (st.com)But it is not clear the method as intervals are weird :I ^4 x t = Cste...
Regarding the shunt resistors connected to the SENSEA and SENSEB pins, the UM1829 has three 0.1 ohm resistors connected. Why is this? The datasheet says one 0.1 ohm resistor.Do I really need three of them?
Hi, Can PD Controller (STUSB4710) act as a DRD?STUSB4710 - Stand-alone USB PD controller (with short-to-VBUS protection) - STMicroelectronicsI believe that STUSB4710 cannnot operate as DRD (Dual Role Data), and can only function as UFP.If there is a ...
Hey, probably a dumb question, but I couldn’t find it in the datasheet. Can each pin of the VNQ9025AJ handle 30A, or is that the rating for the smart switch as a whole with a limit on each pin? Honestly, I’m hesitant to believe a single pin can handl...
I know this is a really dumb question, but I cannot find a definitive answer in the datasheet for the VNQ9025AJ, Quad channel high-side driver with Current Sense analog feedback for automotive applications.There are 4 pins called INPUT0 to INPUT3. Th...
Hi,When I was trying for DC-DC converter design, I have found this VIPer22A Isolated DC-DC converter design. I am having two queries here,1) Is still this technology in use?2) Can I get the details about the transformer which used here?Is there any n...
I have come across this part for my product for alternate part. we are using reset function as separate pin, and we generate 8.3ms of low pulse for reset function to the motor driver. On your datasheet STSPIN820 IC they general given an active low to...
Hi,We are using the chip PowerSTEP01 in our design. In the datasheet, it is mentioned in the application diagram that the VDDIO pin can be powered from the VREG pin. However, the X-NUCLEO IHM03A1 evaluation board design shows that it is powered exter...
Hello. I am using your STP45N FETs in our power supply design for an audio amplifier and we are getting field returns with the STP45N65M5 part damaged. It appears that the gate and source have been shorted but I am not 100% sure. Do you have any insi...
