    Recommend me ASIC with following functions

    Hi gurus, Anybody got any ASIC to recommend with the following functions : 1. with 1x USB interface (preferably 2.0) 2. able to interface with hardisk semelessly (preferably with IDE controller) 3. Ethernet interface 100Mbps 4. A few GPIO for reset button and a probably 3~4 for LED indication...

    Cheap high current sensing solution

    Re: high current sensing So much have been talked about high current sense. Is there anyway to sense a minimum of 10mA to a max 5A DC current ? I have looked at those Hall Effect Current Sensors from Allegro and realised that they could only sense a minimum of 0.3% of their rated current. For...

    How to detect rechargable batteries from normal batteries ?

    how to detect non-rechargeable batteries Hi, How do we actually detect rechargeable batteries from NON-rechargeable batteries ? My focus will be AA size batteries (NiMH, NiCD, Enegizer Photo Lithium and Enegizer Alkaline). In order to implement a dT/dt fast charge termination, where would...

    Could anybody advise me on MOSFET driving circuit ?

    Re: MOSFETS Basic Hi All, thanks for the reply. By connecting a resistor between the Gate & Source for a P-Channel to prevent accidental switching, so how do we size that resistor ? Based on some calculation or simply just a rule of thumb ? Thanks Cheers,

    Could anybody advise me on MOSFET driving circuit ?

    Re: MOSFETS Basic Thanks to E-Design & Hughes. Btw, does anybody happen to know of any MOSFET that have the lowest ON resistance (RDS ON) for about 10V & less than 3A application (preferably SOT-23 package) ? Thanks Cheers,

    Could anybody advise me on MOSFET driving circuit ?

    MOSFETS Basic Hi, Could anybody advise me on MOSFET driving circuit ? Based on datasheet, it is true that the higher the VGS for a N-Channel MOSFET will result in a lower RDS(on) ? And if that's the case, isn't it will be much easier to operate a P-Channel MOSFET than N-Channel since it only...

    Help: designing switching regulator IC (input 3v, output 5v)

    switching 3v regulator Hi, I'm not too sure how much budget you have. Currently, I'm using less than a US$1 solution (mass production) from ON Semiconductor. https://www.onsemi.com/site/products/summary/0,4450,NCP1450A,00.html Take note that the efficiency is not that great as compared with...

    P-Channel MOSFET Common Source Connection

    common source mosfet battery Hi, I have encountered a circuit whereby I could not understand how does it suppose to work. There are 2 similar P-Channel MOSFET (Vishay Si1413) which I shall termed it as Q12 & Q15. Both MOSFET have their gate connected to a single control point which means if...

    TMS320DM310 ASIC able to bootup from NAND flash ?

    Hi, Anybody happen to be using TMS320DM310 (ARM9 + C54) core from Texas Instrument ? Can that ASIC bootup directly from NAND flash ? Btw, does anybody has any programming manual or user guide for this ASIC core to share ? Thanks Cheers,

    Saturation of Inductor Current

    Hi, Whenever a datasheet specs state the IDC of an inductor to be say 1.5A without saturation. What will happen if the circuit current is more than 1.5A (say 2A) ? Will the inductor get saturated ? And when the inductor get saturated, what is the electrical characteristic of that saturated...
