SPV1050 Charging Problem
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...
L99VR02J LDO - how to handle Wi if autonomous watchdog is disabled
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...
Output capacitor selection
Hi,There is no certain information about output capacitor ESR limit value for stabilization. -Input : 5V-Output : 4V @3A-Desired Output Capacitors : 2x10uF 10V Can we use Ceramic capacitors with additional series resistor? In this case what is requi...

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, ...
3 Phase Delta and the EVALSTPM-3PHISO
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...
LDL112PV33R not working. giving Vout same as Vin .
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 ...
Power Delivery possibilities
Hello, I am creating a board using the STUSB4500QTR and I saw something on a video that confused me. I want to use the IC to take in 100W (20V/5A) and output three different voltage rails: 3, 3.3 and 3.7. Each will have a fairly large curren...
Resolved! Download STSW-WPSTUDIO
I bought the STEVAL-WLC99RX evaluation board for the STWLC99 Qi 1.3 compatible receiver and cannot find a location to download the GUI to program/monitor the receiver. The page that I am pointed to (https://www.st.com/en/embedded-software/stsw-wpstud...
BTA41-600BRG stuck ON in some cases
We are using BTA41-600BRG triacs on our temperature control boards to turn on 240V tank heaters. The tank heaters are 1500W, 3000W, or 4500W depending on the unit model and operate at 240VAC. The circuit we are using is attached. We use a FOD4108 dri...
SPV1040 IC Burns
@TDK , @Peter BENSCH we are facing SPV1040 IC failure (burns) in the field, after around 3 months of installation, attached schematic and our solar Panel speciation Voc:4.55V, Vm:3.85V, ISC:1026mA, Im:950mA.Battery spec - 9000mAh, 4.2V Lithium ion.
