Description:

The AS1113-BQFR is an LED driver designed to drive up to 16 LEDs using a high-speed serial interface. It features 16 constant current output channels, with exceptional output current accuracy, making it an excellent choice for high-volume transmission applications. It also includes controlled in-rush current, over-temperature, open-LED, and shorted-LED diagnostic functions, along with low-current test mode and global fault monitoring, allowing for greater flexibility in use. The extremely fast output drivers are suitable for PWM, and the device is available in a 24-pin SSOP or 28-pin QFN package, making it a versatile option for a range of applications.
