Resolved! Voltage regulator to give 2.5V out from 3.3V in
I am designing an interface board where there is an ADC that needs two different power supplies (3.3V and 2.5V). To minimize this board, instead of bringing the two power supplies from outside, I would like to bring only the 3.3V one and through a vo...
Resolved! Calculate stepss for PowerSTEP01 (and L6480)
Hi, I am currently implementing software/firmware for the PowerSTEP01 chip and discovered a inconsistency in data sheet https://www.st.com/resource/en/datasheet/powerstep01.pdf. For parameter INT_SPEED (section 11.1.11 in datasheet) the equation does...
Resolved! STSPIN32F0 Overcurrent detection R43 value
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?
Diode IFSM estimation
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...
Resolved! POWERSTEP01 : sense resistor
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?
Can STUSB4710 act as a DRD?
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 ...
Resolved! VNQ9025AJ Output pin Current capacity
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...
Need Clarification On The Relationship Between INPUT and OUTPUT Pins for VNQ9025AJ
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...
Resolved! VIPer22A Isolated DC-DC Converter
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...
STSPIN820 SDBY/RESET pin pulse and time duration details need
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...
