Part Number: LP55231 I am trying to figure out if 121K ohm resistors are a good choice for pulling up the TRIG, INT, and EN pins on the LP55231. I know section 8.1 of the datasheet recommends using from 120k to 180k "for two devices". What is a good choice…
Part Number: LP55231 Hi support team.
My customer has a question regarding what to do when Dx out is unused.
Is it OK opened for unused output(Dx)?
Best regards,

Part Number: LP55231 Hi All,
if we turn off the I2C & external Clock signal power but the VDD is remain 5V.
Would the output of D1~D9 still be activated?
is there other parts we should notice?
Thank you for your help.
Part Number: LP5012 Other Parts Discussed in Thread: LP55231 , Hi, E2E,
One of our projects used the LP55231 as the main LED driver of the system, for the next revision we would like to replace it with a device capable of driving 12 channels and configured…
Part Number: LP55231 I want to reuse my common cathode RBG LEDs normally connected to LP55231. When LP55231 is not powered, I have a logic circuit that will allow output from the BQ24292 to drive the LEDs via logic gates and a mosfet to source current…
Part Number: LP55231 Our LP55231 is running from a traditional 3.3V rail. However, the microcontroller that provides I2C communication to the LP55231 (and is connected to INT and EN) must be powered by 3.6VDC rail. (I know- it's strange, but there are…

Hi team,
Customer uses LP55231. They has question on the 1x and 1.5x is switched actually on the following setting.
76H is default “0”.
Customer also fix 1x gain to set 36H[4:3] = 01.
But customer still need to know…
Part Number: LP55231 In our design, we use 4 LP55231 with MSP430. After power on, the EN is set to high and everything works fine. In order to save power, we would like the disable LP55231 when MSP430 goes into low power mode. What we did is to set the…
