austriamicrosystems, a designer and manufacturer of analog ICs, has launched an enhanced LED dot-matrix driver that is targeted for dot matrix displays in mobile phones, personal electronics and toys.
The company said that AS1119 requires 9 mm² PCB space and drives 144 LEDs, reduces external component count and connector pin count.
Austriamicrosystems claimed that its new product offers up to 80% extended battery lifetime,and incorporates an 8-bit analog current control that allows fine tuning of each matrix to compensate for different brightness of different colours, or to adjust the white balance on RGB LEDs.
In addition, it incorporates 6 frames of memory for small animations or for use as a buffer to reduce host processor load, and offers open and shorted LED error detection, and low-power shutdown current.
austriamicrosystems marketing manager of lighting Rene Wutte said that the AS1119 enables creative light design with a long battery lifetime through the company’s power management for mobile applications.
"It allows our customers to create unique looking devices while minimizing design effort through the AS1119’s flexibility. The AS1119 also saves space & cost by reducing external component count, reducing connector pin count and the number of PCB layers," Wutte said.
