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.
