GP 30 LED Management

The signal VLED of the CIS is connected to the 24V. The signal GLED is switched on and off by
a port of a ULN2003 (Z202). Three resistor in parallel limits the current to the requested value.
For the 200DPI CIS, the characteristics are:
• 92mA
• Forward voltage of the LED: 13.5V-15V (for 35mA)
Set to 92mA for 200DPI CIS. The source is switched on/off by the signal LED_G. The minimum
forward voltage is 17.4V, the maximum 18.9V, so the source current should withstand a Vce be-
tween xxxV and xxxV, and a maximum power of 1W.
