Hey Christopher,
So SEL pin does not automatically change which Input it picks: If SEL is low and PR1 is High then Input 1 is chosen.
If SEL is low and PR1 is low then Greater supply is chosen.
If SEL is high and PR1 is low then IN2 is selected if inputs…
Part Number: TPS2120 Hi Team,
In my customer charger application, they have 2 power input sources from USB or Qi. The TPS2120 could be used for the input source switching and OVP/OCP protection for the USB input.
I would like to check with you that…
Part Number: TPS2120 Hi TI Team,
I have a question about TPS2120.
If we use the recommended circuit below with 5V and 12V input, and a reverse voltage is accidentally applied at the OUTPUT side, will the device and input still be protected? How will the…
Part Number: TPS2120 hi Sir
I use the TPS2120 to be the power mux, some question need check
1.how about the resistance accuracy require in R71,R65
2.Could you help to check the below circuit is correct?
3.SEL can floating?
thanks
Part Number: TPS2120 Other Parts Discussed in Thread: TPS2121 Dear Sir/Madam,
We found that TPS2120 does not seem to be working correctly. From below graph, Both source 1 &2 are connected to USB-C 5V, when source 2 is unplug, the output dip and cause…
Part Number: TPS2120 Hi,
I am designing a power Mux for our water pump which should be powered up with 8V only at the start up of the device and after 20us we should switch it to 5V.
Therefore the use of TPS2120, so the microcontroller can select the power…
Part Number: TPS2120 Hello TI family,
I have two 14.4V DC batteries in my design. I aim that whichever of these two batteries has the higher voltage value, TPS2120 will give it to the output.
The attached design was made according to the TPS2121 infrastructure…
Part Number: TPS2120 Other Parts Discussed in Thread: TPS2121 , Hello,
I am designing a Power Mux solution for a 12V - 3.5A system. I would have liked to use the TPS2121 but this part is out of stock, with huge delays.
My question is : can I use the TPS2120…
Hello Shreyas,
we tried ordering for EVM free samples with the links which you have shared, but we are not authorized to get free samples. is there any alternate way of ordering.
Thanks for suggesting TPS2121, we have ordered 2 no's of component for testing…
