Part Number: LP55231 Hello,
I would like to ask you a question about the LP55231. (Question 1) When writing 0xFF to the reset register, does ACK of I2C communication return? (Question 2) After writing 0xFF to the reset register, is it necessary to wait until…
Part Number: LP55231 Other Parts Discussed in Thread: LP5813 , LP5861 , LP5018 Hello,
I am using two LP55231 to control 6 RGB LEDs.
When I turn on all LEDs with max brightness, both ICs heat up to more than 80 degrees celsius. I stopped the testing as…

Hi all,
We've been experiencing an issue with LP55231 chips, on at least 5% of boards now. In two instances, SCL has been found shorted to GND. In another instance, SDA and SCL were found…
Part Number: LP55231 Hi,
I have a battery powered low power application. during my device idle mode I get a current consumption of around 40uA. I'm running a test sequence where I:
Power On System -> (Wait 3 seconds -> Enable LED sequence with 2…
Part Number: LP55231 Hello,
I asked about I2C communication when writing 0xFF to the reset register in the thread below.
As a matter of fact, the initialization process works normally with the following procedure. 1) EN to low. 2) Write 0xFF to the reset…
Part Number: LP55231SQEVM Other Parts Discussed in Thread: LP55231 Hi,
We are using two LP55231 to drive 4 RGB LEDs, each chip is driving two LEDs respectively.
Below is the configuration:

Hello,
I am facing some issue in LP55231 with CC1352. With this board I can write sucessfully data write on LP55231, but led is not run. I can also read registers value.
I tryed with other controller and It's working fine.
can…
Hi,
I've seen your problem, and I have some questions for you:
1.In the Github link, I find there are 10 examples and I don't know which one is confusing you.
2.LP55231 has three independent program execution engines, I don't know if you can…
Part Number: LP55231 Hi all
My customer is working on a design with the LP55231SQX/NOPB and they have this question:
Is it ok to use 1uF 10V for the flying capacitors ?
This will help them reduce the BOM lines for their assembly.
The datasheet specifies…
Part Number: LP55231 Hi Team,
I read the datasheet of LP55231. It only specifies the Maximum clock speed, 400 kHz, but not the minimum. Do you know the Minimum clock speed required for the I2C interface?
Best Regards, Tom
