PCA9922 Datasheet | NXP Semiconductors

8-channel constant current LED driver with output error detection Rev. 2 - 6 April 2011 Product data sheet 1. General description The PCA9922 is an 8-channel constant current LED driver designed for LED signage and display applications. The output current is adjustable from 15 mA to 60 mA controlled by an external series resistor. The outputs are controlled via a serial interface with a maximum clock frequency of 25 MHz to allow for the system requirement of high volume data transmission. Each of the 8 channel outputs has edge rate control to limit the change in current when the outputs are enabled or disabled. The device has built-in circuitry for detecting LED open-circuit...
