Part Number: TPS25942A Hello expert, I have question regarding TPS25942A. I'd like to know about the source current limitation but datasheet said it is internally limited. Do this mean internal power path can support above highest current which is limited…
Part Number: TPS25942A Tool/software: WEBENCH® Design Tools Hi,
I have two inputs V1= 12V and V2= 13.2. Does TPS25942A will support these voltages for power muxing because primary voltage is less than secondary ?
Primary power should be taken from…
Part Number: TPS25942A Hello Expert, I have 2 questions for TPS25942. First, could this device apply voltage up to 20V(Abs max) when input side is opened? I think there is no limitation on output voltage maximum rating due to there isn't such a description…
Part Number: TPS25942A Dear team,
My customer are working on Oring design with two of TPS25942A.
One of TPS25942A with 5V input and another with 12V input.
They found that when Vreverse lower than 10mV, the reverse block still work.
Is there…
Part Number: TPS25942A Hello team,
Our customer would like to know why the OUT leakage current in off state is specified for not only sinking but also sourcing.
And they also make sure the conditions for Vout = 18V, V(EN/UVLO) = 0V.
In their…
Part Number: TPS25942A Hi team,
Could you advise the reason why the Cout is 100uF in the typical application of the datasheet ?
Customer would like to put Cout = 10uF or 0.1uF to reduce inrush current.
Are there any concern for the decrease the…
Part Number: TPS25942A Hi team,
In the layout example, there are six vias but customer designed layout and they can place only two vias due to via size.
Are there any concern if the board is placed only 2 vias ?
And also please let me know how…
Part Number: TPS25942A Hi Team,
Here are several questions on reverse OCP.
1. what's the response time, that is, the time between reverse OC is detected to the part take actions?
2. what's the time between the part request to turn off the MOS to…
Hi Yauhara,
It is difficult to review the behavior of TPS25942A without the noise filter removed and tested.
Can you try applying short circuit immediately after the efuse (before the noise filter) and check the device behavior ?
Also, where…
Hi Ash,
Handling 120w through TPS25942A can be a problem since maximum current through it can be 5A but application needs upto 120/12=10A.
Can you elaborate more on end equipment ,what is the application ?
We can come up with a solution using different…
