TLA2528: The output pins on the I2C - status

Geir Instanes

Part Number: TLA2528
Other Parts Discussed in Thread: TCA9535

We are planning on using the TLA2528 on our design and in this design the power will be OFF on the AVDD and DVDD during most of the measurements to save battery. When the device is in OFF state will the I2C bus be in high-impedance stage so the other circuits (TCA9535) can still be in operation?

thanks.

Hello,

The device will not be damaged if you do this, thus is it fine to go forth with this.

As for how the device will affect the I2C bus, I am looking further into and will get back to you. The bus will still be available for other devices to use, but I want to get more detail on this for you

Regards

Cynthia

Hello

Apologies, but unfortunately we do not have any data that looked specially at this scenario.
