The LP5891 is a highly integrated, common-cathode LED matrix driver with 48 constant current sources and 16 scanning FETs. The LP5891 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.
