Part Number: TL431 Tool/software: Hi,
Q1. Difference between TL431/2 and ATL431/2 The reference voltage Typ for TL431/432 is 2.495V, while the reference voltage Typ for ATL431/432 (including LI) is 2.500V. Could you tell me the reason for this change…
Part Number: ATL431 Tool/software: Hello Team,
we are using ATL431 in our new design and we need to know the maximum leakage current as per the Temperature varation,such as for -40 ,25 and 85 degree
in datasheet its provided that the maximum Ioff(Leakage…
Hi Jackson, Sorry for the late response. The source of the problem is the very slow ramp rate of the input voltage, which has insufficient 'overdrive' voltage for the ATL431 to switch from floating to pull-down (~2V). This is discussed in the datasheet…
Hi Joshua,
We captured some waveforms of the ATL431 cathode and Vref pins with respect to ground during a ramp function, load dump pulse, and +50V 2a pulse. The cathode voltage peaked to ~37V during load dump pulse. There were some spikes/ripple on the…
Part Number: ATL431 Hello
My design is using an ATL431B in open loop, as voltage comparator, similar to Fig 30 of the datasheet. As noted in both the datasheet and TI application note slva987a, the output voltage has a small deviation from Vsup as Vin…
Part Number: ATL431 I have failure analysis showing EIPD as result of a catastrophic failure for part ATL431AQDBZR.
Unit2 was proceeded to Deprocess to investigate TIVA alteration site. At Metal1 Seat Metal (TiN) Layer after Metal2 and Metal1 Al Layer…
Part Number: ATL431 Hi Team,
I want to check the input range of REF pin. This pin range can't be seen in DS. Can you share the detailed information with me?
Thanks,
Gust
I initially suspected capacitors and looked very carefully at that. I inspected carefully for signs of cold solder and found now. I removed the capacitors and inspected to find they were not broken. I reinstalled new good capacitors and found no improvement…
Hi Christian,
It is very unfortunate and I am disappointed that the ATL431 did not work out for you. It is very strange that the ATL431 had a strange behavior that I have not seen before.
Best of luck to you.
Ben
