16-channel LED driver has innovative diagnostics function

21 March 2007 Opto-Electronics

austriamicrosystems new 16-channel constant-current LED driver has advanced error diagnostics for open and shorted LEDs. The AS1110 follows the successful AS1109, but doubles the output channels. It uses the serial data input/output lines for the error information read-back, so that no additional PCB tracks are needed for LED error diagnostics. This device is intended for LED displays such as traffic signs, information displays or video walls. This device features 16 regulated ports that provide constant current for driving LEDs within a wide range of forward voltage variations. The currents can be adjusted from 0,5 to 100 mA to control the LEDs brightnesses with ±3% accuracy between channels. The device can be used in multiplexed mode, meaning that a single AS1110 can drive up to 64 independent LED nodes. The built-in LED error detection can be invoked during normal operation, and it can detect any open- or short-circuit as well as an over-temperature. The AS1110 operates from -40 to 85°C, and it comes in a 24-pin SSOP-150 and a 5 x 5 mm 28-pin QFN.
