Part Number: LP8863-Q1 Hello ,
We are analyzing the cause of the LED driver not functioning.
I am observing a waveform at the SD pin that regularly wobbles from about 3.3V to about 12V. What is the cause of this phenomenon?
As for the others, the circuit…
Part Number: LP8863-Q1 Hi team,
Check with you one question, is LP8863-Q1 INT pin output active HIGH or LOW? If some fault is found, INT pin pull high or low?
Thanks.

Part Number: LP8863-Q1 Hi Team,
There is a good new that we DIN LP8863-Q1
And there have one thing need your support!
How does the TI LED driver ensure the Image resolution of different brightness?
Part Number: LP8863-Q1 Hello guys,
One of my customers are looking for a 6ch LED driver which can drive 2 series LED (Vf=3.0V, Total Vf = about 6V) with 100mA at 1ch. Also they need each channel separate analog dimming capability through I2C I/F.
They have…
Part Number: LP8863-Q1 Hi Team
Currently doing a low temperature -40 degree test! When LP8863 adjusts the brightness from high to low or from low to high, the switch block of 8863 will not work! Later, we tested to adjust the input voltage to reciprocate…
Part Number: LP8863-Q1 Hi team,
The action for both Boost OVP High and Vin overvoltage are the same "Device goes to standby and waits until output voltage falls below threshold before restarting.", but one will enter fault recovery and one will not enter…
Part Number: LP8863-Q1 Hi Team,
There is a good new that we DIN TI LP8863ADCPRQ1!
Regarding the GD pin of LP8863, a resistor and a capacitor are connected to the ground. Can the RB7 resistor be replaced with 15 ohm? CB24 is changed to 470pf , what effect…

Due to part shortage, is there a drop in replacement for LP8863-Q1?
I see there is a new LP8864-Q1 & LP8866-Q1 series that are very similar but not pin compatible…
Part Number: LP8863-Q1 Please let me know about two points below for SPI interface clock on LP8863-Q1;
・Is there timing requirement for SCLK rise time and fall time?
・SCLK waveform on rise and fall are occur a little winding, please see below. (1V/div…
Part Number: LP8863-Q1 Hi team,
We now have a requirement for a backlight driver, which requires: 230mA per channel, voltage is 30V, 3 strings of LEDs. Is there any suitable solution recommended?
If not, what is the drawback of making 2 channels of LP8863…
