PCA9306: Application in the air-conditioner

Part Number: PCA9306
Other Parts Discussed in Thread: TCA9517

Hi team,

I have noticed that PCA9306 has win in the Air conditioner. So I have some question for that:

1. What's the application filed of the PCA9306 usually in the air conditioner  

2. What kind of spec of the PCA9306 would the customer care in the application of air conditioner?

3. Why the PCA9306 could be the hero device in the air conditioner? what's the advantage of the PCA9306 comparing with the competitor?

I will appreciate your answer.

Best Regards,

Wesley Huang

  • Hey Wesley,

    "1. What's the application filed of the PCA9306 usually in the air conditioner "

    While I am not an expert on end equipments (like air conditioners), this device typically only has two uses. The most common is level translation, the second use is being used as a switch. I suspect the air conditioner has I2C slave devices which run on different logic levels than the processor and so the PCA9306 is used to translate the different logic levels.

    "2. What kind of spec of the PCA9306 would the customer care in the application of air conditioner?"

    • Operating voltage/level translating voltages 
    • Power consumption/dissipation

    "3. Why the PCA9306 could be the hero device in the air conditioner? what's the advantage of the PCA9306 comparing with the competitor?"

    This is a bit tricky to answer without a specific competitor device to compare to. I suspect that low power consumption in our device would be an advantage. We also provide this device in many packages, if the customer wants to keep their PCB a smaller size to reduce cost then our small packages would be useful.

  • Hi Bobby,

    Thanks for your reply,

    • Do we have better recommendation for the level translation for the white appliance which means the next generation of the PCA9306?

  • Hey Wesley,

    As far as I know, we do not have plans to make a new PCA9306. Other devices which may be a potential replacement for this device would be TCA9517 for its buffering capability.
