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 transmssion applications.
Output current is adjustable (up to 100mA/channel) using an external
resistor (R
EXT
).
The serial interface with Schmtt 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 mnimze
display flicker during fault testing.
With an operating temperature range from-40 to +125°C the
AS1109 is also ideal for industrial applications.
The AS1109 is available in a 16-pin SOIC-150, a 16-pin QFN
(4x4mm and the 16-pin QSOP-150 package.
