Hi guys,
I need help on this circuit. This circuit is used to drive 2 LEDs. U1 and U2 are switch. Their inputs come from microcontroller (I use VDC to run simulation). They dont turn on/off at the same time, 1 is on and the other is off. The below half is a current sink to control intensity of the LEDs.
My problem is I can not completely turn OFF U1, U2. Is there any other way to turn them on/off completely?
Thanks,
