Product Introduction

The LP5892QRRFRQ1 is a highly integrated common cathode matrix LED display driver featuring 48 constant current sources and 16 scanning FETs. One LP5892-Q1 supports driving 16 × 16 RGB pixels, and two LP5892-Q1 devices support driving 32 × 32 RGB pixels. To achieve low power consumption, this device supports independent power supplies for red, green and blue leds through its common cathode structure. In addition, the ultra-low operating voltage range (Vcc as low as 2.5V) and ultra-low operating current (Icc as low as 3.6mA) of LP5892QRRFRQ1 significantly reduce the operating power.

The LP5892QRRFRQ1 implements a high-speed rising edge transmission interface to support a high number of device Daisy chains and high refresh rates, while minimizing electromagnetic interference (EMI) to the greatest extent. The LP5892QRRFRQ1 supports up to 50MHz SCLK (external) and up to 160MHz GCLK (internal). Meanwhile, this device integrates enhanced circuits and intelligent algorithms to address various display challenges in narrow pixel pitch (NPP) LED display applications as well as Mini and micro-LED products: The dimming of the first scan line, double images at the top and bottom, unevenness in low gray scale, coupling, and caterpillars caused by open or short circuits in the LED make the LP5892QRRFRQ1 the perfect choice for such applications.

The LP5892QRRFRQ1 can also perform LED open circuit/weak short circuit/short circuit detection and removal during operation, and can report this information to the accompanying digital processor.
