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.
LP5891属于集成电路(IC) > LED 驱动器。美国德州仪器公司制造生产的LP5891LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列,可通过标称固定电压的电源为负载(通常为发光二极管)提供电流,并且电流可控。它与用于电压调节的类似产品的主要区别在于,这类器件提供较低的反馈电压(以提高系统能效),而且通常可对器件工作点进行外部控制,可在照明应用中用于实现调光功能。
