Questions about VNB35N07TR-E device
Dear ST Team, I hope this message finds you well.I am currently working on a new design project for [mention the application or product type if applicable] where we are considering the VNB35N07TR-E component. I have several questions regarding this c...
TC4469COE713 multi output error
Hello, I purchased this IC and would like to use it to alternately control four different inputs so that the IC’s four outputs can switch sequentially. However, I'm currently facing an issue: I’m only providing input to a single channel, e.g., Ain, b...
Resolved! LDL212
LDL212-3.3v DFN (2x2) Running Superhot With LDL212Heat Dissipation (Power Dissipation)The power dissipation PP can be calculated using the formula:P=(VIN−VOUT)×IOUTP = (V_{IN} - V_{OUT}) \times I_{OUT}Where:VINV_{IN} = 6.65V (input voltage)VOUTV_{OU...
Resolved! VN9D5D20F what does "Reverse battery through self turn-on" mean?
The datasheet for the VN9D5D20F lists "Reverse battery through self turn-on" as a bullet point under "Protection", while the VN9D5D20FN datasheet does not. This appears to be one of the major differences between the two parts, but I do not understan...
USB PD Load Sharing
Hello, we are searching for a USB PD Power Budgeting/ Load Sharing solution. Here an example: Lets say we have 4 USBC PD Ports. All in all they sould be able to source 60W. One port is sourcing 15V/3A=45W, then the remaining 4 should just be able to ...
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...
