A S 110 9
Constant-Current, 8-Bit LED Driver with Diagnostics
1 General Description
The AS1109 is designed to drive up to 8 LEDs through a fast serial
interface and features 8 output constant current drivers and an on-
chip diagnostic read-back function.
The high clock-frequency (up to 50MHz), adjustable output current,
and flexible serial interface makes the device perfectly suited for
high-volume transmission applications.
2 Key Features
?? 8 Constant-Current Output Channels
?? Excellent Output Current Accuracy
- Between Channels: ±2%
- Between AS1109 Devices: ±2%
?? Output Current Per Channel: 0.5 to 100mA
Output current is adjustable (up to 100mA/channel) using an external
resistor (R EXT ).
?? Controlled In-Rush
Current
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 AS1109 also features a low-current diagnostic mode to minimize
display flicker during fault testing.
With an operating temperature range from -40 to +125°C the
AS1109 is also ideal for industrial applications.
?? Over-Temperature, Open-LED, Shorted-LED
Diagnostics Functions
?? Low-Current Test Mode
?? Global Fault Monitoring
?? Low Shutdown Mode Current: 3μA
?? Fast Serial Interface: up to 50MHz
?? Cascaded Configuration
?? Fast Output Drivers Suitable for PWM
The AS1109 is available in a 16-pin SOIC-150, a 16-pin QFN
(4x4mm) and the 16-pin QSOP-150 package.

3 Applications
The device is ideal for fixed- or slow-rolling displays using static or
multiplexed LED matrix and dimming functions, large LED matrix
displays, mixed LED display and switch monitoring, displays in
elevators, public transports (underground, trains, buses, taxis,
airplanes, etc.), large displays in stadiums and public areas, price
indicators in retail stores, promotional panels, bar-graph displays,
