STEVAL-ILL035V2

Оценочная плата для драйвера светодиода LED7708.

The STEVAL-ILL035V2 is an slave evaluation board for LED7708 LED driver. The LED7708 is a 16 channel, 85mA LED driver with boost controller and 4 wire serial interface. It has been specifically designed to supply several LEDs from a single low voltage rail. It has sixteen current generators rated at 40V and a 4 wire serial interface to control LED brightness. These channels can be put in parallel for higher output currents. A selectable 12bit or 16bit gray scale brightness control allows independent PWM on each channel. A programmable on chip dimming oscillator is provided to simplify external circuitry. The device has dedicated pins to lock synchronize with other devices (master or slave) for noise reduction in multi device applications. The LED7708 implements basic protection, as well as LED array protection. It can detect and manage open LED and shorted LED faults and different fault management options are available in order to cover most application needs.
