Part Number: TPS2121 We are using TPS2121 (Power Mux with Seamless Switching) for Power multiplexing two input power sources in Primary and Secondary sources combination.
There is a glitch during transition from primary input source to secondary input…
Hello Patrick,
Thanks for response and feedback on our comments.
Any other comment for schematic which was already added in first conversion.
We used bidirectional TVS diode at input of IC Pins. So, there will be any chances to failure/ damage of Oring…
Part Number: TPS2121 Hi Experts,
Is it acceptable to use the TPS2121 under the following conditions?
When there is no power supplied to IN1 or IN2, an independent 3.3V is provided to PR1. During power-down, the 3.3V to PR1 is dropped after IN1 and IN2…

1. Yes, I believe tSET and VOUT rise time should be similar across CSS values.
2. Unfortunately, we don't have any tSET data published in the data sheet.
Thanks,
Patrick
Part Number: TPS2121 Hi team,
We are using TPS2121 Power Mux in our design. During testing we observed the following issue. When only IN2 of TPS2121 is connected to 5V supply, no output is seen. Attached schematics for your reference. Please let us know…

I would like to ask for a small review because I need to get this right the first time around :-)
I'll buy an EVK and test it, but writing about it should also help discover any possible issues (and the EVK won't make the diode…
