Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
We noticed that there are pulses at the gate drive outputs (pins 15 HVG, & 11 LVG) during the ramp-up of the control voltage (pin 12 VCC).This is what we saw: when VCC reaches about 11V, a sequence of pulses appear on both LVG and HVG. First LVG went...
Question 1:In our circuit Pin 5 STBY is pulled down to 0V to instantly stop pulses on gate drives. But sometimes when STBY=0V we still see pulses at the gate driver outputs LVG, HVG. The datasheet does not mention that gate pulses may still happen.I ...
Dear All,I would like to ask for your help in the following topic. I've got a new task to develop a special balancer to lift up different weights (from 20 to 50kg) without the need of changing it's spring force. The weight of the products has to be m...

Hi,in STUSB4500 if we are planning to use the chip for Power delivery and communication enabling circuit, then will it be necessary to do adjustments in the Vbus when and external 3v3 is applied to the Vsys pin.In case of a Power delivery available p...
I just assembled my EDUKIT01 and getting my feet wet. I downloaded all the available PDFs, files, etc. from https://www.st.com/content/st_com/en/campaigns/educationalplatforms/motorcontrol-edu.html and also from the https://sites.google.com/view/ucla...
My schematic is exactly as shown on page 26 of https://www.st.com/resource/en/datasheet/stusb4500.pdf with an ESP32 connected to the I2C pins and a BQ2057WSN downstream on Vsnk. However, on connection to USB-C the chip negotiates an explicit 5V powe...
