Hi all
Would you mind if we ask TPS767D30?
<Question1>
How much is the sink capacity at reset pin?
<Question2>
How much of the minimum value resister can be set at reset pin?
Kind regards

David san,
Thank you for your prompt reply!
We know that it is specified for 1mA maximum to output 0.4V, at a Vin of 2.7V on the datasheet.
We guess that the sink current of Reset depends on internal FET's Absolute rating current.
By increasing the sink current of Reset, the voltage at Reset increases.
That's why, how much is maximum Iout the sink current?
Or, is internal FET's Absolute rating current 1mA?
If internal FET's Absolute rating current isn't 1mA, dou you have as following characteristics or figure?
<For example>
Iout=1mA/Vout=0.4V
Iout=2mA/Vout=0.5V?
Iout=3mA/Vout=0.6V?
Iout=4mA/Vout=0.7V?
We need your help.
Kind regards,

David san,
Thank you for your reply!
Ok, we got your circumstance.
By the way, why is Sink current of the test condition defined Io=1mA?
You mentioned that 1mA is not MAX continuous current value of FET.
So, if you know, could you let us know what Io=1mA means?
Kind regards,

David san,
Thank you for your reply!
Ok, we understood that the test conditions mean that they force 1mA into the RESET.
The internal FET can likely sink more current but test condition is forced 1mA.
Is our recognition correct?
