t4UFunctional description
eIZ1517 – digital CMOS IC of light emitting diodes control with opportunity of selection of LED
eoperating mode, single button start mode, automated turn-off function. It has embedded RC-
hoscillator with typical 100 kHz frequency, inside current-limiting resistors 75 Ohm. Recommended
Soperating current on LED pins – 20mA. LEDs operate with duty j. Duration of turn-off delay – 8
taseconds. Possibility of modification of mode, rate, duty and duration of operation during fabrication
aof layer «metal» is envisaged. Design features
