austriamicrosystems has expanded its LED driver offering with an LED driver suited for full colour applications such as LED video displays, LCD TV backlighting, indoor/outdoor full-colour LED displays and large-size stadium displays.
The AS1112 offers an integrated PWM of 12 bits with 4096 greyscale steps per colour, reaching up to 68 billion colours with RGB. Additionally, the integrated 6-bit dot-correction allows adjusting the output current in 64 steps to compensate for LED luminous mismatch. The device offers high accuracy of ±4,5% between channels and ICs, line regulation of 2,5% and load regulation of 0,5%.
The AS1112 features 16 regulated current ports which provide constant currents for driving LEDs within a wide range of forward voltages. The output ports are guaranteed to endure a maximum voltage of 15 V, allowing multiple LEDs to be combined in series to a single pixel to increase brightness. Currents can be adjusted from 0 to 80 mA via an external resistor.
The IC's built-in LED error detection can detect any open- or short-circuit as well as any over-temperature occurrence. Two temperature thresholds allow detailed thermal surveillance of the system. For immediate detection of errors a global error pin is available; furthermore, a detailed error report can be read out with the exact position of the broken LED. The AS1112 uses the serial data input/output lines for this information so that no additional PCB tracks are needed for LED error diagnostics.
The fast 30 MHz serial interface of the AS1112 ensures high refresh rates even for huge LED display modules. A power-down function reduces the supply current to 40 nA in standby mode. The IC has an operating temperature range from -40 to +85°C and is available in the small, thermally efficient 32-pin TQFN (5 x 5 mm) package.
