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 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…
Part Number: TPS2121 Hello,
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…
Hi Pooja,
I came with the similar situation. Have you ever solved this? In my case, 0.5A load, IN1(12V) drop then switch to IN2(8V) works ok, but IN1(12V) recover from 0v to 12V, expected switch from IN2(8V) to IN1(12V) haven't happened, and a 38ms long…
Part Number: TPS2121 Other Parts Discussed in Thread: TPS2117 Hello, I want to reduce the Iq of 300uA on TPS2121.
Since there is no enable pin available, can i use the SS pin to disable the Mux.
To keep the Mux in low current disable state, I plan is…
Part Number: TPS2121 Other Parts Discussed in Thread: LM66100 Hi TIer
I would like to inquire about TI's TPS2121 dual-channel power multiplexer, which can be used in positive voltage. It meets our current usage requirements in positive voltage. However…
Hi Patrick, Thank you for your reply.
The green trace is a downstream component's output. The downstream input and TPS2121 Vout are connected, and the UVLO value of the downstream input is set to 4V.
Additionally, I tested by changing the hysteresis…
Part Number: TPS2121 Is there an adapter board to prototype the RUX package?
Would also be interested in a "foot" to allow conversion from RUX package to DIP (or SOiC or something).
Thanks!
