Part Number: TPS2116 Tool/software: Hello:
The customer is debugging the TI chip TPS2116DRLR chip, and a single chip is abnormal. Please help analyze it.
Abnormal: When VIN2 is powered normally, when the preferred VIN1 is inserted, that is: USB_C_VCC…
Part Number: TPS2116 Tool/software: I am currently considering a circuit using the TPS2116.
This time, I want to operate it in Primary MODE.
Is there a problem with connecting PR1 directly to VIN1 in this case?
As long as VPR1 > VREF (=1V), I don't think…

Hello,
Since the original post was closed, I open a new one. I initially opened this post https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1351746/lm66100-vin1-floating-pulldown…
Hi Gorka,
We had a look at your schematic and we don't see any issue with this setup. There's no concern of voltage from one channel affecting the other, and there's no reason to be concerned about reverse current unless you're planning to add additional…
Part Number: TPS2116 Tool/software: Hello,
We have implemented the "TPS2116DRLR Power Switch 2.5A SOT-583" IC in our product.
Instead of the recommended output capacitance of "100uF capacitor" , we have opted for a "47uF SMD 1206 Ceramic…
Part Number: TPS2116 Hi,
I am trying to use this dev kit to test out my application. here is the setup
VIN1 -- 3.3V li-ion battery
VIN2 -- 3.3V li-ion battery
The end goal is ..
if VIN1 goes below 2.5V switch to VIN2.
Doesn't matter what i set the PR1…

Hi everyone,
To feed a custom measurement system, I need to manage three different power sources (5V): 2 power inputs from two USB ports (VUSB1 and VUSB2) and one from a wall block PSU (VEXT) keeping in mind that I want to priotorize…
Part Number: TPS2116 Tool/software: Is there any problem in using only one of VIN1 or VIN2 with voltage applied?
If there is no problem, could you please let me know the precautions when using it?
When one customer was testing a power multiplexer for…
Part Number: TPS2116 Hello,
In the circuit below, I switch between the 5V input of VIN1 and the USB VBUS of VIN2.
The operating mode is priority mode.
I am currently experiencing the following symptoms.
1. When VIN1=5V input and VIN2=floating, the same…
