Ben Kuo said: But once we set P0/P1/P2/P7 of TCA9549 as output , we can scan and find TCA9539 slave device on I2C bus.
May I know why we need to write command to wakeup TCA9549?

There is no P2P replacement, and no other device using the single-wire protocol.
You would need to use an I²C expander, either TCA9536 with four bits, or one of the many TCA95xx 8-bit expanders.
Hi Dejan,
From what I have gathered so far, you are attempting to interface with 15 different sensors with 15 different unique I2C addresses? In such case, why do we need an external device such as the PCA9536 to make this work? Since each device has…
Part Number: TCA9544A Other Parts Discussed in Thread: TCA9536 , Hello
I´m trying to start some I2C communication with some preasure sensors.
On the I2C bus there are 3 participants.
TCA9536 (Addr: 0x41) - to switch on/off power for sensor - communication…
Part Number: PCA9536 Other Parts Discussed in Thread: TCA9536 Hi
One customer has question for the POR function of PCA9536. Can you help to check and give some comments? Thanks.

We noticed an errata in TI PCA9536 datasheet, stating chip lockup…
Bond, James Bond (007),
I assume you are referring to the rise and fall times, as well as other timing specs (like data hold and valid times). If you violate these, the PCA/TCA9536 will most likely just NACK your request.
Worst case scenario, if you…
