Found some P channel devices, price range 1. Also, it has to be be able to put out 1 amp in voltage regulation all the way up to 2 amps ideally with no sign of going into non voltage regulation mode.

Potentiometer Questions Started by norbss Yesterday at That would be very cool, especially if it was just the one USB lead.

Im going to be looking into this more and finally i’ll be building up the circuit. Articles Top Articles Search resources. Forums New posts Search forums. This actually reduces satasheet length of the on period. Hi MrRB, Oh yeah pretty nice! Replacement Transformer Started by ncag Today at 7: The program board i have does it that way too to regulate the 12v program pulse amplitude.

Hi MrAL, sorry I don’t have any tablet experience at all, not owning one. The reason i bring this up in this thread is because im doing all this for a Tablet computer anyway, and also that if you havent used one for your test equipment you may be interested in looking into that.

What i’d like to do is use the Android Tablet the same way, even if it means creating new software for the Android environment rather than Windows. Operation is pretty simple; the PIC has 2 ADC channels, and monitors the battery voltage and current sense resistor voltage. No way around it.

I was wondering if you might have some notes on this or if not if you would be interested. I started a new thread about this subject a few days ago: From what i have read now some dont work and some do, so it’s a toss up.

I was thinking of an entire inverted scheme, but this looks interesting too. The charger automatically selects between 7. Click here to dahasheet now. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

The external 3406a allows currents up to a few amps at good efficiency, datasheey I have used hard current limiting at 1. So the bottom line is an interface to the Tablet that allows various uC based test equipment to connect and use the Tablet as display and eventually control input too. I think i can wing it with the parts i have, especially once i read that line from fernando which might help too cause i have so many N channel devices on hand.

12v to 5v DC high efficiency SMPS buck converter using 34063 IC.

But also it would be nice to be able to use that BASIC language as that would give me the ability to change the program even if im not near to a PC to do dafasheet Android programming Java or whatever. I was looking for about 1 amp nominal output current with up to 2 amp capability. Here’s how the board turned out, tidied up a bit and neat enough to be buried deep in a robot chassis.

It’s basically discontinuous, or very close to it, and quite erratic looking. I added a datasheer angle shim and large sloder blob to cool the PFET which now never gets much warmer than body temp.

So with the parts values I chose it was peaking on the current limit and in sync with the inductor ripple and the internal oscillator.

Oh ok, that’s an app note about gate drivers I thought it was an app note that pertained directly to that chip.

I take it you can write tablet apps like a program to display the voltages? The Tablet load could be represented by a load that changes in value like a lower to higher resistance and then back again depending on mode of operation either strictly running the device or both running and charging or just charging, and if charging what state the battery is in.

I’ll read it and see what it has to offer then get back here with some comments. Right now i have constructed quite a while back actually a four channel ‘meter’ that can measure voltages and with some simple interfaces can measure current too. That allows easy testing of battery cells of just about any type very versatile set up capabilities which allows testing of four cells simultaneously.

Oh ok, they also include home made boot strap drivers, which is a nice change. Hi MrRB, Well, i am aware of how a peak current limit works in regulators but that’s not really the kind of regulation i would need for this project.

It is shown for a N-chan Fet, reverse the diode and transistor polarity. To participate you need to register.

For a better experience, please enable JavaScript in your browser before proceeding. This language allows quick changes right on the Android Tablet so i can set up different things quite easily. These are stacked so to get battery voltage it reads the current then subtracts that reading from the voltage to give true battery voltage.

The has two types of regulation; the normal voltage regulation has a fixed on period and fixed frequency, and will skip on periods or cut some on periods in size to maintain voltage out. By continuing to use this site, you are consenting to our use of cookies.

What other interfacing options does datadheet tablet have? Let me elaborate just a little. It could be the Linux ones work but im not sure datashete as i am quite new to this operating system and hardware. The board above was adapted to now become a high efficiency smart charger for a 6v battery.
