Hi Team,
I used LP8866-Q1 in my application and found the INT pin was pull low. So I checked the BOOST_STATUS to see the fault event. The data is 0x1000h which means that ISET_CLEAR = '1'.
But we check that our RISET is…
Part Number: LP8866-Q1 Hello,

Part Number: LP8866-Q1 Hi Team,
We used MCU to provide PWM input signal to LP8866 and we found when we waked up MCU, the control pin had a pulse to LED driver.(LED driver was enabled then.)
Does it affect LED driver to have fault behavior?
Thank you…
Part Number: LP8866-Q1 Hi Team,
My customer told me that our I2C R/W bit are error. R/W=0/1, but it should be R/W=1/0.
I don't have tool on my side. Have you ever heard this error from other customers?

Part Number: LP8866-Q1 Hello,
How should PWM_FSET pin be terminated for direct PWM? Does it require a register to GND listed in the table 7-8 in p.26 of the datasheet? But the registers such as 3.92k may be unavailable and/or expensive. Is it OK just…
Part Number: LP8866-Q1 Hi ,TI:
We use the LP8866 chip, and the I2C pin is used as dimming, but we also need to feedback the error (such as overcurrent, undervoltage, overvoltage) return value to the main control chip. My problem is that the I2C interface…
