Before my question this is the assumption - I am assuming Supply sequencing is same - within ASIC which has many power domains, and within ICs which are sitting on Board. 1. What is the need of supply sequencing within ASIC which has multiple power domains. 2. If we don't follow it what are the violations? 3. How to catch them during ASIC d
SCR might stay latched on, probably a bad choice. An "avalanche rated" MOSFET might solve the problem cleanly, depending on the stored energy. Should be app notes / selection info for any such parts. A "catch diode" that returns overshoot energy to the supply could also do the job, less dissipatively than the TVS (TVS will have a Joule energy pe
UVM learner it is easy to set a "default bins" as below. A : coverpoint data { bins a = {0}; bins b = default; //catch all values that do not lie within any of the defined bins. } but how to implement a "default coverpoint" in following example? A1 : coverpoint data { bins a = {0}; bins b = {3};
I agree with Klauss. It is highly unlikely that the failure is occurring on the mains side of the circuit. Most likely you are getting spurious pulses from the triggering circuit. (Whatever that is). The trick is to catch those spurious pulses. Do you have a storage scope?
Yes, you will destroy the battery and it might explode or catch on fire. Modern cell phones use a Lithium battery. Lithium is a very powerful, volatile metal and a Lithium battery must be charged properly by a good battery charger circuit designed for the battery. Your "charger" is not a charger, the Lithium battery charger circuit is inside the p
A lithium battery will blow up or catch on fire if you do not correctly charge it by limit the charging current, limiting the maximum voltage and disconnecting the charger when it is detected to be fully charged. Your "charger" is not a charger, instead it is the power supply for the charger circuit inside the phone. The charger circuit for
Hi. I have the following simple circuit that switches on a resistive load that is approx. 6A. 130464 I am using a diode rated at 200V, 1A as the catch diode. This is a S1DL. I measure the current through the diode and it never reaches more than 2Amps for less than 5us. This is well within specification. I actually use
Hi , 1) I use IRF640 in H-Bridge circuit , this mosfet has o
How about using morse code instead with a completely non-standard set of characters. Of course those with ham radio experience might catch on faster then the typical riff-raff. The method you are proposing would be very very easy for a bystander to pick up, besides taking forever to enter.
Thanks for your advice, BradtheRad! Although far-fetched..it's looking more like that may be the case. Was watching about an hour ago the footage of them working last night. When they were getting ready to leave, we see one of them (who we believe may be using his phone against the cameras somehow) walked around a big enclosed area, which is all c
Hi, I'm trying to model a sinusoidally driven harmonic oscillator using RLC circuits using LTspice IV. I get a reasonable result for the series RLC circuit, but not for the parallel circuit. Can anyone catch what I'm missing? Ideally they should both give me the same result. Attached files show circuits and AC analysis results.
You also need a circuit to detect "low battery" when a cell voltage has dropped to 3.2V then it disconnects the load. If you discharge a cell to below about 3.2V then it is permanently ruined and might catch on fire if you try to recharge it.
Don't you know that Lithium batteries explode and/or blow up if they are charged or discharged wrong? The latest Boeing airliner: Lithium battery fire. Hoverboards: Lithium battery fire. Most couriers will not ship lithium batteries: because they might catch on fire. The metal called Magnesium also ends with "ium" and it also burns like crazy. Same
Perhaps you wish to catch the maximum readings? During every 1/50 sec? Or 1/10 sec? Or 1 sec? Then this might be a job for a sample-and-hold circuit. It depends on what amount of detail you wish the data to contain (for instance, waveform as jackhammer makes single break through concrete). Also depends on what timeframe of data you require (for
If you try to charge a Lithium battery from a voltage regulator without using a proper battery charger circuit then the battery will probably catch on fire. Do not try it because Lithium burns at a very high temperature and it is difficult to stop the fire since I think water on it makes it burn hotter.
They invite 'partners', which means investors. Their claims are spectacular. Could there be a 'catch'? Something they're not telling us? Something that renders their device impractical? Need for super-cooled equipment, for instance? Will their device outperform competing devices? R&D teams around the world are trying to invent the next step in min
Hi, This may be a solution. (But I really don't know where the OP exactely sees the problem) But with a timer delay of 2s it is not possible to catch the 15s point. Maybe this is the problem of the OP, maybe not. With a 2s delay the timing could be: 0s - ON - 2s - OFF - 4s - ON - 6s - OFF - 8s - ON - 10s - OFF - 12s - ON - 14s - OFF - 15s - co
hello So I can use the try,catch command in keil?
I check that others have made footprints very often. I use a really long checklist - it has over 85 checks on it. I am expected to tick or comment on every one of them - what a PITA that is!! But it does remind me what to check for and can catch some things that I forget. For consistancy: I use a spreadsheet for every bit of a part, symbol & comp
Disclaimer - I am very very new to Electronics (literally a week), but am doing a lot of reading to try and catch up with the knowledge I need for my eventual project. Background: I run a lot of endurance running races and almost all of the races use UHF RFID passive chip timing systems where the runners wear a UHF passive RFID tag embedded in
