Part Number: PCA9536 Hi,
P0-3 has an internal pull-up resistor of 100 kΩ.
P0-3 goes High at startup.(Before register setting)
I want to set the P0-3 output to Low at startup using pull-down resistor.
What is the minimum value of the pull-down resistor…
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…
Part Number: INA236 Other Parts Discussed in Thread: TCA9536 , TMP102 , PCA9536 , INA238 , INA228 , INA226 , INA237 I am using 5 x INA236 devices in the design. They are living on a single sided MCPCB, so signal routing is very limited. The issue is that I…
Part Number: TCA9536 Other Parts Discussed in Thread: PCA9536 Hello,
I have noticed that when I write to registers 0x01, 0x02, and 0x03, it does not seem like the first 4 bits are being overwritten. Just the second 4 bits are modified. The unmodified…

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,
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…

Hii Sir,
I am trying to build dts file for SPI flash Memory(W25Q64) through AM335x Processor but I am getting like this "recipe for target…
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…
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…
