AS1130 I²C Interfaced, Ultra-Compact, 132 LED Driver IC

ams' LED drivers with full color crossplexing for home appliances, lighting effects, and personal fitness applications

Image of ams' AS1130 I²C interfaced, ultra-compact 132 LED Driver ICams’ AS1130 is a compact home appliances, lighting effects, and personal fitness applications LED driver for 132 single LEDs. This LED driver can be programmed via an I2C compatible interface. The AS1130 offers a 12 x 11 LED-matrix with 1/12 cycle rate. The required lines to drive all 132 LEDs are reduced to 12 by using the cross-plexing feature optimizing space on the PCB. The whole LED-matrix driving 132 LEDs can be analog dimmed from 0 mA to 30 mA in 256 steps (8-bit). Additionally, each of the 132 LEDs can be dimmed individually with 8-bit allowing 256 steps of current adjustment on each matrix for up to 3 mA per LED. To reduce CPU usage, up to six frames can be stored with individual time delays between frames to play small animations automatically. The AS1130 operates from 2.7 V to 5.5 V and features a very low shutdown and operational current. This LED driver has a temperature range of -40°C to +85°C and comes in three packages: 28-SSOP, 28-TSSOP, and 20-WLCSP. The AS1130 is ideal for home appliances, lighting effects, and personal fitness applications.
