Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hi, We have integrated the STWLC38 as receiver for our device. We want to know how to read the registers to know the status of charging, voltage and Current. https://github.com/STMicroelectronics/STWirelessCharging-C-Drivers/tree/main this gives patc...
Hi all, I'm using a L6482H on a PCB with STM32F439VIT6 to drive a stepper motor. MCU and driver are connected via SPI. I have an issue with the GetStatus command; when the switch input on the L6482H is closed and the driver receives a GetStatus comma...
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...
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...
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...
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...
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...
