Description
General part information
LP5891-Q1 Series
The LP5891-Q1 is a highly integrated, common-cathode LED matrix driver with 48 constant current sources and 16 scanning FETs. The LP5891-Q1 implements a high speed rising-edge transmission interface to support high device count daisy-chained while minimizing electrical-magnetic interference (EMI) and internal GCLK rate ranges from 40 MHz to 160 MHz. The device also implements LED open/weak-short/short detections and removals during operations.
The LP5891-Q1 is a highly integrated common cathode matrix LED display driver with 48 constant current sources and 16 scanning FETs. Besides driving 16 × 16 and 32 × 32 RGB LED pixels as LP5890, three LP5891-Q1 devices are capable of driving 48 × 48 RGB LED pixels and stacking four LP5891-Q1 devices can drive 64 × 64 RGB LED 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 LP5891-Q1 is significantly reduced by ultra-low operation voltage range (Vcc down to 2.5 V) and ultra-low operation current (Icc down to 3.6 mA).
The LP5891-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 50-MHz 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 LP5891-Q1 a perfect choice in such applications.
