Part Number: LP8863-Q1 Tool/software: Hi TI-team, We have upgraded our led-driver design to handle led strings at a higher voltage. A few years ago we had a thread about outputs with higher voltages ( up to 54V ) and your advise than was to add 10M resistors…
Part Number: LP8863-Q1 Tool/software: Hi! The pulse voltage was measured with LED0 when VDD was turned on. Since the pulse waveform was measured even when the cathode and anode sides of the LED were open, we believe that the pulse voltage is coming from…
Part Number: LP8863-Q1 Tool/software: Hi all,
I was wondering if someone can help me with a problem I have come across. I have three LEDs and I want to link them to separate clusters. I have set LED0 to the register DISP_BRT which is the display brightness…
Part Number: LP8863-Q1 Hi team，
Customer 8863 has a black screen. I checked the register and found that this register is set to 01. I see that 1 is reserve. Under what circumstances will this register be set to 1?
Part Number: LP8863-Q1 Tool/software: Hi team,
In my understanding, when use power line FET and R_ISENSE, soft start is enabled.
In soft start, Cin is charged softly? My customer measured inrush current on Cin.

Part Number: LP8863-Q1 Hi,
The LP8863-Q1's current and brightness values for the LED channel registers are maximum (0xFFFF) by default.
I am currently using the EVM board and an Arduino via I2C but wish to include this driver in a PCB design.
When…
Part Number: LP8863-Q1 HI all,
I have a question regarding ISET specification.
I am doing the measurement of ISET PIN during the operating condition and got the result 1.37V. Please confirm which specification was correct. Because in datasheet it has…
Part Number: LP8863-Q1
Hi All.
I have a question regarding the LED Driver,
During the operation, if the LED Driver has fault, What is the best way to disable the LED driver back light? 1. PWM setting = 0
2. Disable the enable pin
Or Do you have another way…
Part Number: LP8863-Q1 Hi all
I have some question regarding the LED Output String
1. In LP8863 Datasheet the LED Output String is automatically detected " read" only, and we cannot set the register, but in LP8863-Q1 Automatic String Detection…
Part Number: LP8863-Q1 Hi,
R&D has some questions regarding the LP8863s LED Driver Currently R&D is verifying the LED Driver, and we use the I2C register to set the LED Driver, For the LED Output String, we use 6 Channels with Automatic Phase Shift…
