Description

Electronic devices are becoming smarter, requiring to use larger quantity of LEDs for animation and indication purposes and high performance LED matrix driver is required to improve user experience with small solution size.

The LP5890 is a highly integrated common cathode matrix LED display driver with 48 constant current sources and 16 scanning FETs. A single LP5890 is capable of driving 16 × 16 RGB LED pixels while stacking two LP5890s can drive 32 × 32 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 LP5890 is significantly reduced by ultra-low operation voltage range (Vcc down to 2.5 V) and ultra-low operation current (Icc down to 3.9 mA).

The LP5890 implements a high speed 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 and up to 160-MHz GCLK (internal). Meanwhile, the device integrates enhanced circuits and intelligent algorithms to solve the various display challenges in multiple LED matrix applications: Upper and downside ghosting, Non-uniformity in low grayscale, Coupling, and Caterpillar caused by open or short LEDs, which make the LP5890 a perfect choice in such applications.

The LP5890 also implements LED open/weak short/short detections and removals during operations and can also report this information to the accompanying digital processor.
