144-LED Cross-Plexing Driver with 320mA Charge-Pump
1 General Description
The AS1119 is a compact LED driver for 144 (90) single LEDs. The
devices can be programmed via an I²C compatible interface.
The AS1119 offers two blocks driving each 72 LEDs (3 blocks each
30LEDs) with 1/9 (1/6) cycle rate. The required lines to drive all 144
(90 )LEDs are reduced to 18 by using the cross-plexing feature opti-
mizing space on the PCB. Every block driving 72(30) LEDs can be
analog dimmed from 1 to 30mA in 256 steps (8 bit).
Additionally each of the 144 (90) LEDs can be dimmed individually
with 8-bit allowing 256 steps of linear dimming. To reduce CPU
usage up to 6 frames can be stored with individual time delays
between frames to play small animations automatically.
The AS1119 operates from 2.7V to 5.5V and includes a 320mA
charge-pump to drive also white LEDs. The charge-pump operates
in 2:3 and 1:2 mode.
The AS1119 features very low shutdown and operational current.
The device is available in a ultrasmall 36-pin WL-CSP.
