Part Number: PCA9536 Hi All,
Can anyone tell me what the typical (or max) standby current is for the PCA9536 with all the I/O set for outputs? The datasheet only covers the case with the I/O set as inputs.
In my application, the outputs will be set high…
Part Number: PCA9536 Hi Team,
Please help to confirm the thermal information of PCA9536DGKR. Data sheet doesn't show Θjc.
Also, how to calculate its power dissipation? Please kindly provide the formula.
Thanks
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: PCA9536 hello,I am new in I2c protocol . I am using PCA9536 i2c expander as a slave in my project. My goal is to read the slave address( i.e.,0x41) .I was tested with arduino board it works well. But i am tested with nrf52 dk it does not…
Part Number: PCA9536 My customer would like an i2c I/O expander with a reset function so they can ensure the device will be in a known state. They are looking at the PCA9537 from NXP. We do not have a direct cross. Do we have any I/O expanders with this…
Part Number: PCA9536
A silly quick question, can someone help me confirm that this is Pin #1? The package doesn't match that shown in the datasheet , just wanted to confirm before using!
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…
