Part Number: PCA9536 Other Parts Discussed in Thread: TCA9534A Hi,
I am using PCA9536 in my design. I see that the device behavior is not constant. Every time I power up the behavior is different. Sometimes it works fine and sometimes it pulls the line…
Other Parts Discussed in Thread: PCA9536 , TCA9536 Hello I2C Experts
if the PCA9536 is powered at eg. nominal Vdd = 3V and the Vdd then drops below 2.3V ( Vdd min in dada sheet ) but stays above POR voltage and then goes back to 3V..
What will happen then…
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…

I would like to use PCA9536 to keep Output mode for our application in C5515.
Please provide Init code example code and output mode example code.
Thanks.
Best Regards,
Thank you Eric. It appears then, I have the updated/correct part installed. Good news/bad news situation.
Sure. I'm not seeing the I2C signals on either of the two outputs on the device.
A snippet of the design is shown below. I2C_SCL/SDA signals…
Hi OL,
Checking the PCA9536 datasheet 0x41 is the correct slave address to use. It may be a hardware related issue, that's the first thing that comes to mind.
Can you confirm proper circuitry and connections for the PCA9536 device? Feel free to share…
Other Parts Discussed in Thread: PCA9536 I have a question about the Iq for the PCA9536. It lists two modes for standby (see below). I'm not sure whether Vi is the I2C port or the I/O port. I can't imagine why the output port being low would cause the…
Hello, Thank you for your answer. Unfortunately, there is still the same error message, even with this correction. It seems that the problem comes from the configuration because I have the same problem each time I try to read a register (that one or another…
