Part Number: LP8864S-Q1 Other Parts Discussed in Thread: LP8860-Q1 Hi team,
Are there calculator tools for LP8860-Q1 and LP8864S-Q1 that can be provided to customers for design assistance? If so please help send it to me.
Part Number: LP8864S-Q1 Hi team, my customer have a question about R_LED_SET, What is the maximum allowed error for the resistors? is it 1%? is there any detail calculation formula?
Part Number: LP8864-Q1
Hi Sir,
My customer would like to know the LP8864-Q1, when they use the minimum components condition, does it support the output short and LED short protection?
Part Number: LP8864S-Q1 Hi team,
My customer want to know about open/short detection and OV, OT.
1. open/short detection
In my understanding, threshold is a LED output voltage not a current. And its voltage is represented in Fig.7-18.
According to datasheet…
Part Number: LP8864-Q1 Hello TI Team,
LP8864-Q1 is set in Phase-shift PWM mode and the input PWM frequency is 211Hz.
When doing below operation, the dimming on-time doesn't change:
The input PWM on-time had met the PWM detector hysteresis requirement…

Part Number: LP8864-Q1 We tested the OUT1 and bootout/GD waveforms as follows: When the backlight is 5%, the OUT1 and GD waveforms do not match 1. Waveform at 95% brightest backlight:
2. Waveform when backlight is 5% darkest:
Additional schematic…
Part Number: LP8864-Q1 During the software debugging process, it was found that when using IIC to communicate with the backlight chip Lp8864, the data reading was normal, but the data writing was invalid. After investigation, it was found that during…
