Dear Arush,
Thanks for you help and we finally solved the issue.
When the TPS22919 switches off the voltage at the output will drop.
During the drop of the voltage there is a point where the SELECT pin of U16 TMUX will pass a voltage of 1V. (see the…
Part Number: TPS22919-Q1 Tool/software: Hello experts,
My customer asked me whether there is any requirements for IN pin and ON pin power sequence. E.g. ON high => IN high or IN high => ON high @ turn-on, ON low => IN low or IN low => ON low @ turn…
Part Number: TPS22919-Q1 Other Parts Discussed in Thread: ADS7038-Q1 , ADS7038 Tool/software: Why we need to consider NC pins of an IC while performing package failure mode distribution ?
Part Number: TPS22919-Q1 Other Parts Discussed in Thread: TPS22919 Tool/software: Hi TI,
I want to use 1.8V for ON pin to enable TPS22919.
On datasheet, I understood It can use to enable IC. But I want to make sure and double check.
Can I use 1.8V…
Part Number: TPS22919 Tool/software: Dear e2e support,
Can we elaborate a bit more on the failure mode of our TPS22919?
In case of failure, does-it go into short circuit, open circuit, high impedance, ...?
Regards,
Part Number: TPS22919 Other Parts Discussed in Thread: TPS22950 Tool/software: Hi,
Would like to check if there is a load switch with short circuit current limit lower than 900mA (preferably <600mA), and able to do lower sequencing (OQC and EN pin).…
Hi Ansel,
I missed this thread. I think I did reply back to you on mail regarding the Cin question.
Ansel F said: For my 2nd question, should I expect that the output voltage of the load switch could be as high as VIN due to the leakage?
Are you seeing…
Part Number: TPS22919
Hello,
In a LiPo charger circuit, the battery voltage is input to a TPS22919, and the output of this component is then controlled by a power switch circuit.
If the battery is charging, when TPS22919 is disabled, Vout is 0.480V
If…
Part Number: TPS22919-Q1 Hi Expert,
Do we have tps22919-q1 curve of On-resistance vs load current? Vin=3.3V System load current=400mA
If we have, would you mind sharing the curve with me?
Kind Regards
Imelda
