VSTORE and LDO2 Voltage Drop When Loading STEVAL-ISV019V1
[Moderation] Separated from the previous thread, as the STEVAL-ISV019V1 is a different topic. Hi,As the questioner mentioned, the voltage measured on the STORE pin is about 2.416V. Should we charge the battery at this time? What conditions can raise ...
Resolved! Vac sense circuit of STEVAL-7BIDIRCB
Dear ST community, I'm reviewing the Vac sense circuit of STEVAL-7BIDIRCB, where the circuit uses a resistor divider to generate a low voltage of VACN and VACL for MCU. I simulated this section of circuit in LTspice, and here is my result : My Vac in...
How energy flows in STEVAL-HARVEST1
Are there any more resources to understand how to use STEVAL-HARVEST1, how does the energy flow from super capacitors to the MCU and also the back up capacitors. I feel few things are missing the schematic and the user guide. I want to first implemen...
Resolved! STSPIN840 Setting overcurrent values
Is the overcurrent protection set to 3A on the STSPIN840? If so, is there a way to change the trip value of the overcurrent protection to better align with its application? I want to change it so that the overcurrent trips at 1A. Thank you!
Resolved! How to set STUSB4710 PDO profiles
Hi, I am designing a 25W power supply for the raspberry pi 5 for my battery powered project. The buck regulator I am using has a fixed 5V output and I want to use the STUSB4710 to offer 5V 5A to the Pi. How can I program the registers to do so via I2...
STUSB4710 PD-Source Configuration Without Feedback
Hello,I am using the STUSB4710 as a PD-Source in my project and have a few questions regarding its configuration. In my setup, I have not utilized the feedback configuration. Instead, I am connecting the PDO outputs of the STUSB4710 to a microcontrol...
Resolved! L9961 Cell voltages deviate during discharge
Hello, we are having an issue where our cell voltage readings are drifting when discharging. When there is no current, the voltages all read correctly. However, during discharge, we see that cell 5 and cell 1 have lower voltage readings by about 150m...
Resolved! STTH10002's Humidity working range
Hello to all, I am looking for the min-max humidity working ranges of the STTH10002TV1 diode (in %) as I can't find it in the product specification.Is there a general value for all the ST's diodes? If so, where can I find it ? Thank you for your time...
STPM3x Calibration Setup Understanding
Good morning,I currently have my final design ready but I am struggling to understand the meter calibration setup in AN4470. Below are images of how to setup to meter a load as per UM2066 and also how to setup the meter for calibration as per AN4470....
