3 Description
The LP5892-Q1 is a highly integrated common
cathode matrix LED display driver with 48 constant
current sources and 16 scanning FETs. One LP5892-
Q1 supports to drive 16 × 16 RGB pixels and two
LP5892-Q1 devices support to drive 32 × 32 RGB
pixels. To achieve low power consumption, the device
supports separated power supplies for the red, green,
and blue LEDs by its common cathode structure.
Furthermore, the operation power of the LP5892-Q1
is significantly reduced by ultra-low operation voltage
range (Vcc down to 2.5V) and ultra-low operation
current (Icc down to 3.6mA).
The LP5892-Q1 implements a high speed rising-edge
transmission interface to support high device count
daisy-chained and high refresh rate while minimizing
electrical-magnetic interference (EMI). The device
supports up to 50MHz SCLK (external) and up to
160 MHz GCLK (internal). Meanwhile, the device
integrates enhanced circuits and intelligent algorithms
to solve the various display challenges in Narrow
Pixel Pitch (NPP) LED display applications and mini
and micro-LED products: dim at the first scan line,
upper and downside ghosting, non-uniformity in low
grayscale, coupling, caterpillar caused by open or
short LEDs, which make the LP5892-Q1 a perfect
choice in such applications.
The LP5892-Q1 also implements LED open/weak
short/short detections and removals during operations
and can also report those information out to the
accompanying digital processor.
