Part Number: LP8860-Q1 Hello,
I would like to ask you a question about LP8860-Q1. The figure below shows the waveform at startup. Depending on the device, some devices maintain a constant output voltage during the 50ms BOOST START period, while others reduce…
Part Number: LP8860-Q1 Hi,
The register LED_CURRENT is calculated including the PWM?
If not, it means the value of the register is exactly the current that configured in register DRV_LED_CURRENT_SCALE?

About LP8860-Q1 pwm PIN Settings
In datasheet
BRT_MODE original value is 10, directly through the IIC to write 00, read later, found 10. It's not changed to.
Excuse me, do not burn EEPROM, How to setting PWM pin.
Part Number: LP8860-Q1 Hello TI expert,
We are using TI LP8860 backlight chip, in our design we make the Cathnod of the 3x LED strings shorted together in display side as below picture.
Check the LP8860 datasheet seems connecting the LEDs Cathnod…
Part Number: LP8860-Q1 hello experts:
at my use case , the led panel let the backlight LED cathode connect together and the LED cathode connect the LP8860 three leans , i want to know if there any issue with this use case ?
Part Number: LP8860-Q1 Hi team,
Is the customer in the project? Due to a manufacturing error, the three-way connection between the light string and the chip OUT (OUT1/OUT2/OUT3) was mistakenly connected together in the connector design. As shown below…
Part Number: LP8860-Q1 Hi team,
If the customer only uses three strings of backlight, will there be any problems if mode0 is selected, will there be an error message, OUT4 is not connected in MODE 0 state, what is the state of OUT4?
Is it necessary to…
Part Number: LP8860-Q1 Hi team,
When the customer was testing the frame, the initialization screen on the head unit side was normal (xxxx), and then the instrument backlight failed to be sent (16:00), and the instrument was black (16:50). The instrument…
Part Number: LP8860-Q1 Hello!
Could you please help me out about LP8860-Q1 identification. In the datasheet there is no value given for FULL_LAYER_REVISION and METAL_REVISION. What is the expected values of the ID register (0x12)? Is it possible that the…
Part Number: LP8860-Q1 Other Parts Discussed in Thread: TLC6C5712-Q1 Hello, Team,
The boost circuit of LP8860-Q1 seems to determine the output voltage based on a switching frequency. We think that in case of 2 RGB LEDs in parallel *(i.e. Vf = 2~3V * 2…
