Part Number: TPS22994
Hi Team,
Posting on behalf of our customer.
We are working with TPS22994 for power muxing of several devices.
We have a power source (which may be on or off). We have some Device Under Test (DUTs) which should be powered…
Part Number: TPS22994 Tool/software: Dear forum
I want to use a TPS22994 to switch the outputs of four TPS6223* converters.
The TPS6223* seems to be optimised for a 4.7 uF output capacitor, even tough 2 - 15 uF should be ok (datasheet, page 13, section…
The initial question was really about my usecase of the TPS22994 by bridging inputs and the outputs getting effectively a single channel handling around 2 amps. Looking at the lastest release (2014 :-)) of the datasheets actually has this usecase added…
Part Number: TPS22994 I'm currently using the load switch TPS22994 and have a question on the resistance I should be seeing before a power up. I currently have the ION pins tied to ground and see a very low resistance at the Vout pins before a power on…

i'm looking for a compact quad channel load switch & found TPS22994 to be a suitable candidate to propose to my client. Hence i will need more details…
Part Number: TPS22994 Hi,
I'm evaluating the tps22994 for a project and have created a simple breakoutboard for it. Having issues getting the i2c mode to work.
Question: Is it a correct assumption gpio mode will not work ones i2c mode has been turned…
Part Number: TPS22994 Other Parts Discussed in Thread: TCA9535 Hi TI-team
Can TPS22994 be used in a vacuum environment （10^-5 Pa）?
Pa is pascal.
What is the minimum usable barometric pressure ?
If the above is impossible, what is the minimum…
Part Number: TPS22994 Hello,
I would be grateful for some answers if anybody has experience in designing with the TPS22994 power load switch. It is a quad channel load switch that contains a special function (SwitchALL) that allows multiple devices…
Part Number: TPS22994 Hello,
I am planning to make an only GPIO control from TPS22994. Can I leave SDA, SCL, VDD floating or should be grounded? ADDx should be tied to ground? Preferably at cold boot I want them to be turned OFF, how can I do it?

Hi Jason,
Because the VBIAS supply is below 4.6V, VIN must be 1V below the VBIAS voltage for proper operation. Please see the excerpt from the datasheet below:
Therefore, for a 3.6V VIN voltage a VBIAS voltage of 4.6V should be used. With your current…
