Datasheet
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 (R
EXT
).
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.
