Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hi! I'm using the STP16CPC26 as an LED driver, but have a problem where all the attached LEDs initially flash when powering up. This is a problem since this is a UI with a large-ish number of LEDs and you get hit right in the face with the bright fla...
We have approximately fifty modules in the field that use the L6981CDR. The schematic below shows how they are connected. The L6981CDR is used (in combination with other components) to generate an output voltage of 5V. This output voltage is used to ...
Hi ,Recenlty I designed the my custom board with LDL112PV33R . My Vin is from Battery charger BQ25620 which is 3.7V. Now LDO giving directly 3.7V at Vout. I done following diagostics. check marking on IC which ic ''L112 33''. which is indicating Fix ...
We're using this controller in our project and have the VCC pin tied to VBUS so the device does not pull power from the battery when USB is not connected (it was pulling ~125uA which is too much for our battery life as the main power is not turned of...
There are already a few posts which show there is an issue with getting the STSW-WPSTUDIO GUI downloaded. I replied to one, but I have yet to receive a response. I am looking to select capacitors to tune an RX coil connected to a STWLC38JR controller...
HelloCurrently, all information on WBC86TX and WLC38RX has disappeared from the ST homepage.Does this mean that the two chips are discontinued?I would like to know whether they should not be applied to new designs,and how long they are planned to be ...
Hello,I designed a circuit, but there is a problem with it. My supercapacitor (C5) is charging very slowly. I am using Dracula's standard OPV. It receives an average of 500 lux. It is charging so slowly that it is almost not charging at all. What cou...
I have an application where I am using L99VR02J. for this application I do not need the watchdog so I have tied Vcw to Vo as specified in the datasheet on page 22."Since the RST output pin is shared by the watchdog circuit and the output voltage moni...
Hello everyone,I’m trying to locate the DSMPS 3kW – LLC STM32F334x firmware package, which is described as containing the following folders:Documentation – includes compressed HTML and LaTeX help files generated by DoxygenDrivers – includes HAL, LL, ...
I have the EVALSTPM-3PHISO. IT appears that it only measures Volts and amps on a single phase at a time, then switches to a different phase for 3 consecutive phases. We are working with Delta power (no neutral). Do the Sample and hold on the ADCs get...
