1 / 24 page  AS1113 50mA, 16-Channel LED Dri v er with Diagnostics Dat a Sh eet www.austriamicrosystems.com Revision 1.00 1 - 24 1 General Description The AS1113 is designed to drive up to 16 LEDs through a fast serial interface and features 16 output constant current drivers and an on-chip diagnostic read-back function. The high clock-frequency (up to 50MHz), adjustable out- put current, and flexible serial interface makes the device perfectly suited for high-volume transmission applications. Output current is adjustable (up to 50mA/channel) using an external resistor (REXT). The serial interface with Schmitt trigger inputs includes an integrated shift register. Additionally, an internal data register stores the currently displayed data. The device features integrated diagnostics for over- temperature, open-LED, and shorted-LED conditions. Integrated registers store global fault status information during load as well as the detailed temperature/open- LED/shorted-LED diagnostics results. The AS1113 also features a low-current diagnostic mode to minimize display flicker during fault testing. The AS1113 is available in a 24-pin SSOP and the 28- pin QFN (5x5mm) package. If a higher output current is needed, please see the AS1110 with 100mA drive capability. Figure 1. Main Diagram and Pin Assignments 2 Key Features ! 16 Constant-Current Output Channels !
