3 Description
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.
