  • RE: ATL431: PSpice model problems...

    Hi Jeff, I will get a product expert to help you out with this by tomorrow. Thanks, Abhinav.

  • ATL431: wave soldering

    • Resolved
    Part Number: ATL431 does any one help us if ATL431 supports wave soldering. best regards,

  • ATL431: ATL431 details Question

    • Resolved
    Part Number: ATL431 Hi Team I want to know why the Ikamin of ATL431 is much smaller than TL431

  • ATL431: Vref Accuracy

    • Resolved
    Part Number: ATL431 Hi, I'm considering Vref accuracy as below on typical condition and -40℃~85

  • ATL431: ATL431 disable

    TI Thinks Resolved
    Part Number: ATL431 Hello support team, In ATL431 datasheet Fig4, when VKA=VREF=0V, is IKA current same as Ioff :0.05uA? If VREF is pulled low, can ATL431 be disable with very low current? Customer would like to investigate ATL431 as over voltage...

  • RE: ATL431: Output Unstable

    Hi Kevin, Lets discuss this over email. -Marcoo

  • RE: TL431: Voltage monitoring circuit

    Hi Muhammad, Reducing R6 R7 and R8 will lower the voltage drop due to the leakage current because the TL431 is not fully off as per the app note which works. If you want to save IQ. I would suggest a ATL431 or ATL431LI which have much lower leakage...

  • RE: ATL431: Reference Current

    Hi SRW, 1. I would include the IR drop as an error. So the trigger worst case voltage would be approximately 2.5V + Rin*I(Rin). The IR drop will cause the REF pin to see a lower voltage. As you mentioned if a voltage divider is used, then the resistor...

  • RE: ATL431: IKA value when VKA is not equal to VREF

    HI Hiroshi-San, See my feedback below: Q1: We do not characterize the device since this device is used out of its normal mode of operation (closed-loop). The behavior is interesting since the delta should not be that high when REF is under 2.5V. ...

  • RE: TINA/Spice/ATL431: SPICE model is incorrect?

    Hi Naoki, The oscillation could be a stability issue on the ATL431. I am discussing this issue with our modeling team and see if we can fix this issue on the next release. -Marcoo
