So it looks like there are 2.5W or 15W reference designs, does anyone have a 5W reference design?
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 ...
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...
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...
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...
I have the following situation:I have a custom PCB with a 4 port HUB ic on it (TUSB8041IRGCR). The UFP of the hub is connected to my phone and there are 4 DFP.My phone negotiates with the PD controller via CC lines about what voltage it wants when p...
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 ...
