Okay so, currently wanting to set up a test for some rechargeable batteries, and developing a lower power mode for a system. The goal is to connect fully charged batteries to my devices to see how much current they actually drain. I have an estimate how long they should last, but its not exact...

Hello guys, so i have an electric sit stand desk and it stopped working a while ago, i opened up the control box model TC15L from TI motion, and saw the IC in the pictures was fried so much so that it was impossible to read the part number off of the IC. Upon touching this IC, it blew away like...

Hello, I wanted to reach out to this wonderful community to seek some guidance regarding an issue I'm facing with the DS26LV32 and DS26LV31 ICs on my board. I believe your collective expertise and experience can help shed some light on this problem. In my current project, I am utilizing the...

An inductor of inductance 80mH, 500 A at 60 Hz needs to be designed. But my area product is coming too high. Probably because of VA rating. Due to this I can't find a suitable core that matches its Ap. Please help me with calculations of Ap. Is there something I am doing wrong? My voltage comes...

Hi here is the schematic for my A7672s Simcom module i want that how i can improve this power section for my simcom so that it can run for longer years i hope got it so i want your support that what all are the espect and factors to design and selections of good life longer component for smooth...

Hello everyone ! I'm planning to buy a 30w solar panel to attach to my two redundant powerbanks that will be constantly powering my rasberry pi which will be connected to the internet too. Such project I would use to plan building a drone too... I think that would be cool. I have a doubt...

AC DC rechargeable Led bulb driver mainly build with two different ICS. First one is drive several leds in series when power is available. Second one is drive several leds in parallel, also charge the lithium battery, when power cut happens the second IC drive the leds in parallel using the...

I am using a IR2101 gate driver circuitry to switch the high side IGBT ON (I do not want it to be periodic). Hence I found out that since I am not frequently switching the IGBT, the bootstrap circuitry doesnt not work since the capacitor cannot charge up. I therefore found out 2 ways I can...

Hello everyone, I de-soldered a 24-pin IC from an old Uninterrupted Power Supply's board. However, I haven't been able to find a datasheet or even information about the manufacturer on the almighty internet so far. Here's what I've been able to find out from looking at it closely: What I...

Hello, I am working on my 2018 GMC instrument cluster. It has a parasitic current draw that drains the battery within 3 days. I found this part which to me, looks like and SMD diode. It is reading "OL" in circuit and out of circuit. See attached photo. I have tried looking through the SMD Code...

Dear All, Currently, l am working on a project where l need to differentiate the led behavior due to light or color intensity. The aim is to identify the end of fade in /out and the beginning of slow blinking in sequential processes. l want to identify how long fade in/out and slow blinking...

I want to buy a MOSFET in the rating of 600V/20A. I also want to buy MOSFET driver for that. I have to use it with Arduino Uno for controlling purpose. But I can't select which one to buy. Can anyone suggest me a good MOSFET + MOSFET Driver?

I’n looking for a wireless EMS/TENS units which could be controlled by computer. I would need this for research to vary stimulation length and timing based on other sensor readings. I can find online only customer TENS units that can be activated using predefined programs. I would be ready to...

I am using seven segment in my project and i was using common cathode and using npn transistor i was able to switch by making arduino pin HIGH. But now i want to display the data on seven segment when i make the pin as LOW. I mean i want to select the Segment when i will make it LOW. i was...

Hi, Not sure if best to post in general chat or power electronics, but: I am having some significant issues when measuring my power converter capacitances with a hand-held LCR meter than I expect from the specification. I have a series-parallel combination of capacitors that should give an...

I am making a boost converter following this Tutorial but I don't have the exact MOSFET. I have 2 motherboards laying around and they have some MOSFETs on them some of the names are: P3055, K3918,6670AL(datasheet inserted). There are high switching speeds but the datasheets don't have the max...

No doubt a High-quality metal construction Design with Flexible silicone nozzle for better seal for suction. Majority of the buyers keeps on complaining about the issue while ejecting the waste solder. Solder get stuck in the silicone nozzle and they find it difficult to unclog it. I believe...

Is there any way to connect 3.5mm TRRS to F-6188 v4.0.

Good afternoon to everybody. First post over here! :D I am working on the estimation of junction temperature from top case temperature measurement. I have seen that manufacturers avoid the characterizing the molding this resistance which is crutial for this purpose. From now on I will take...
