Texas Instruments LP5890 48x16 LED Matrix Drivers

Texas Instruments LP5890 48x16 LED Matrix Drivers are highly integrated common cathode matrix LED display drivers with built-in SRAM to support 1 to 32 multiplexing. These drivers support separated power supplies for the red, green, and blue LEDs by the common cathode structure to achieve low power consumption. The LP5890 drivers implement a high-speed transmission interface to support a high device count daisy-chained and high refresh rate while reducing Electrical Magnetic Interference (EMI).

The LP5890 drivers feature low grayscale enhancement, 16 scan line switches with 190mΩ RDS(ON), 48-current source channels from 0.2mA to 20mA, and low EMI Continuous Clock Series Interface (CCSI). These drivers are used in LED digital signage, keyboards, smart speakers, audio mixers, wireless and wired speakers, and gaming accessories.
