Hi Alberto,
We do not specify what happens when the absolute maximum ratings are exceeded. For your specific example, 12V will certainly damage the module and break the silicon devices inside. It is possible that when the silicon breaks, it shorts and…
Thanks for explaining.
You need more protection and capacitance on the input for an automotive environment. They are many harsh voltage spikes that normally occur on the battery rail. This reference design shows one type of simple protection method…
Hi Luciano,
The TPS82130 is not a -Q1 (automotive) device.
We have the TPS62130A-Q1 which is. See this reference design for an example of an OVP circuit: http://www.ti.com/tool/PMP9757 You will need some sort of protection if you plan to connect this…
I believe all these devices just require ~5V. Each of these devices has an internal battery charger which just needs a supply voltage. A solution like this can convert the 12V battery to 5V: http://www.ti.com/tool/PMP9757
Hi,
It looks like your input GND connector is not connected to the GND plane on bottom layer.
It is only connected on the top layer.
Now the input current return path is only connected through some vias and fairly long.
You could try to add a thick…
Yes, you can clamp above 17V for your situation. I would ask you to measure the Vin right at the IC's pins with a scope to see the real waveform.
More input capacitance is another possible solution. As well, a series element like a small resistor…
Yes, as applications engineers it is our job to assist customers with their applications. This is a very popular device family and used by many many customers. Being so popular, there are many questions, issues, unique configurations being discussed…
