LED driver with front panel activity control

22 July 2009 Opto-Electronics

austriamicrosystems has released the new AS1115, an easy to use user interface (UI) LED driver. It combines display driving and key scanning, providing a complete front panel solution. The device can drive either eight 7-segment digits or 64 individual LEDs with 47 mA per digit or 5 mA per LED. An external resistor can be used to adjust the current. With accuracy of ±3%, the AS1115 improves picture quality for LED displays, due to minimised intensity variations between the LEDs and LED modules. A 4-bit PWM is implemented for either global digital brightness control or separate dimming of each single digit. Additionally, the device offers read back of up to 16 keys. The AS1115 features built-in LED error detection which can detect any open- or short-circuit within the multiplexed 8x8 LED array.
