Part Number: LP8860-Q1
Hi, TI
We use LP8860-Q1 EVM, and download software GUI. we found different with datasheet as below chart.
Datasheet: EXT_TEMP_MINUS[1:0] 1,5,9,13uA, but GUI show 2,6,10,14uA.
it`s normal? or setting wrong?
And about T1 (Knee)…
Part Number: LP8860-Q1 Hi team,
My customer is designing this device and their thermal engineer would like to evaluate whole system thermal performance.
So they need to know how to calculate LP8860-Q1 IC power dissipation for survey.
Please help to provide…

Dear Support Team,
I have some question about LP8860-Q1 as below:
1. Pin11 (Fault pin) is normall open or normall close? if input voltage was turn off, how to know the Fault signal output? if IC error, the Fault pin is continued…
Part Number: LP8860-Q1 Hi team,
customer try to read LP8860-Q1 reg via I2C, sometimes will report NACK and fail to read it.
the signals of below pictures from up to down are LP8860 SDA; LP8860 SCL; SOC SCL and SOC SDA. SOC is mater to read LP8860-Q1. …
Part Number: LP8860-Q1 Hi Ti engineer ，
There is a failure on the drive board made by lp8860-q1, and the after-sales service indicates that there is a breakdown of the diode of the lamp board. After the lamp bar is connected with the NG board, the Lightbar…
Part Number: LP8860-Q1 Hi Team,
I have a few questions from my customer about the LP8860-Q1 monitoring registers that I could use your help/thoughts on:
Register 0x13 - TEMP MSB
How often does TI recommend to check the TEMP data over I2C?
- Minimum or…
Part Number: LP8860-Q1 Dear TI team,
are there any suggest component values (red boxes) for the circutry needed to us a nFET for power-line control on LP8860?
Are there any impact on input voltage functional range or any other important impacts by using…
Part Number: LP8860-Q1 Hello,
my customer is using LP8860-Q1 for an automotive display application.
PWM output frequency is set to = 5kHz
From the datasheet we were not able to determine the minimum ON time of LP8860 at lowest dimming ratio. Looking…
Part Number: LP8860-Q1 Hello
