Part Number: LP3943 Hello,
I would just like to confirm, the I2C address of this device is 1100(A2)(A1)(A0), correct? and A0-A2 is just a 0 or 1 depending on the voltage at the corresponding pin?
Best regards,
Zach Kimble

Hi Sir,
would like to check with you about the “Data hold time” requirement on LP3943. Base on I2C standard version 7, the “Data hold time” just meet 0us, not 300ns…
Part Number: LP3943 Tool/software: Hi Sir,
We would like to control all LEDs blinking synchronize at the same time.
Is it possible to make all LEDs on and off at the same time by setting PCS0, PWM0, PSC1, PWM1?
1. When set DMI0 blinking rate for…

Part Number: LP3943 Hi Experts,
I am writing to know how to select these resistance (the red mark on the below picture).
Is there any consideration in the selection of resistance?
Thank you for the help.
Part Number: LP3943 Hello Team,
what is the recommendation for unused LED channels design and configuration wise. As I understood the open drain inputs/outputs can be left floating when they are turned OFF?
Thank you

Part Number: LP3943 Hello,
I would like to confirm, is it possible to individually vary the LED intensity with the LP3943 and could that be controlled through software? I would like to clarify how to control LED brightness per channel, thank you!
Part Number: LP3943 Hello,
I want to drive RGB and white LEDs using an I2C driver. I have read the datasheet of LP3943 and i don't understand the meaning of the LED Vih min = 2V. It means that the voltage on LED port must be always greater than 2V…
