Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
I have some questions regarding the L78M05AB regulator IC.1. Could you please investigate the temperature at which this IC's the thermal protection actually activates?2. I have been informed that the thermal protection mechanism shuts down the output...
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...
Hi, The L9945 driver used in our proprietary automobile controller unit responsible for controlling actuators and pumps in exhaust system regulating harmful exhaust gases adhering to emission control policy. Case1: OUT 2 channel: Nominal frequency = ...
Hello,I'm migrating STSW-STPM004 firmware from IAR to STM32CubeIDE (GCC).The metrology_STPMS2.a library was compiled with IAR and causes UsageFault(CFSR=0x00008200, INVSTATE bit set - ARM/Thumb interworking issue)when linked and run with GCC.Is ther...
Hi, Im using the L9963E for a Battery Management System. I noticed that the device has a register called "FSMstatus". I don't understand if reports the current status or the previous status. For example, if the device is in SLEEP, in order to read t...
Hi everyone,I am designing a custom Power Distribution Board (PDB) handling up to 200A at 24V. This PDB will eventually interface with an STM32 and a Jetson Orin Nano for telemetry and control, but my current focus is solely on verifying the robustne...
I am testing the board with a 14s Li-ion battery, but I am unable to read the cell voltages or configure any register through the GUI. I shorted the X1 and P2 power supply inputs and supplied 12 V to both. This was the only setup in which I could g...
can someone help me with communication of l9961 chip to get voltages of 4s cells n current n charge accumulated by using esp32 or aurdino i dont have this chip n i am not a coder i tried my best but can get any data from the chip just i2c add 0x49 n ...
Hello, we are in the process of developing a BMS using an STM32 and L9961. We were wondering if there was any source or example code of a full BMS we could have access to in order to speed up our development. I am aware of the example code on the pro...
