Part Number: LP5891-Q1 When designing a RED LED 114X90 Dot by applying LP5891-Q1, Should I configure the ICs as 3X2 and apply 38 DATAs and 15 SCANs to each IC?
Part Number: LP5891 Hi all,
I'm working on a custom board with 2 LP5891 in cascade mode, no reversed mode line activated.
The screen is a 94x30 pixels in monochrome. Line missing is the firt (L0) and the last (L31) due to mechanical constraints.

Part Number: LP5891 We are planning to implement an automotive screen using Samsung RGB Mini LEDs (LED Driver IC LP5891). While discussing with Samsung, I heard that it is difficult to realize 24FPS screen frame when using TI MCU. The LED Driver IC internal…
Hi Hiroaki Yuyama,
Yes, considering that is challenge for customer so we provide the whole system solution. Below figure show the solution and the EVM board can request in the official website.

How is V.knee defined?
In the data sheet, the maximum knee voltage is reported as:
V.knee.max @ V.cc = 2.8 [V] @ I.channel = 10 [mA] = 0.30 [V] …
Hi Nathan Kando,
Nathan Kando said: Are T.high.min and T.low.min static values for all T.cycle, or are they dynamically dependent on T.cycle (without this being indicated in the datasheet)?
the T.high.min and T.low.min are same for all T.cycle which i…
Hi Ti experts,
If I want to light up a 60x60 LED matrix, how many ICs should I use, and how should I configure it in the demo code?
Do you have an example code for cascading multiple units?
Part Number: LP5891 Other Parts Discussed in Thread: , , LP5890EVM Hi team,
The datasheet has example setup for Four Devices Stackable Connection, which has VLEDR and VLEDG/B separated. Would you please share why those are separated?

Part Number: LP5891-Q1 Other Parts Discussed in Thread: LP5891 , LP5890 , LP5861 Hi everyone,
Based on the datasheet, LP5891-Q1 is using DS-PWM Algorithm where one frame will be divided into sub-periods and each sub-periods will be divided into 32 segments…
Part Number: LP5891 Other Parts Discussed in Thread: LP5890 Hello Team,
I have a single string of 86 RGB diodes.
I was thinking the LP5891 could address it by using the 16 RGB channels and 6 lines.
By each refresh of the line, does the current source…
