The A8517 provides protection against output short and overvoltage, open or shorted diode, open or shorted LED pin, shorted boost switch or inductor, and IC over-temperature. Output voltage adapts to variations in LED VF for optimum efficiency and open LED faults do not affect the operation of connected LED strings. Therefore dimming ratios up to 65,000:1 (256:1 PWM, 256:1 Current DAC) can be supported. If you'd like to quickly turn off all the outputs, raise the OE pin - it's pulled low to enable the PWM outputs.Our Arduino library will get you started with blinking http://powerelectronics.com/lighting-systems/10-channel-led-driver-automotive-apps

If needed, the IC can drive an external P-FET as input-disconnect switch that is triggered by an integrated current sense. Allegro's™ A8517 integrates a current-mode boost converter with internal power switch and 10 I²C programmable current sinks, and can provide 5,000:1 contrast ratio PWM dimming at 200 Hz. You can drive multiple LEDs in series, with a V+ anode supply of up to 30V. For volume-specific price or delivery quotes, please contact your local Linear Technology sales office or authorized distributor.
The LEDs can be dimmed to one of 256 levels, programmed through the I2C/SM-bus interface.
