48 × 16 LED matrix driver with 16-bits PWM dimming and ultra low power

Texas Instruments

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.
