Hello,
I am using a MAX4623CSE chip (http://pdf1.alldatasheet.net/datasheet-pdf/view/73426/MAXIM/MAX4623CSE.html) and having trouble understanding how it works. I have Pins 13 and 14 to ground, Pins 12 and 11 to +5VDC, Pin 1(COM1) to a power supply, and Pin 16 (NO) to a simple LED circuit (current limiting resistor then LED connect to ground all in series). From my understanding, when Pin 15 is brought high, +5VDC, it will close the switch and allow current through. Then, when it is brought to ground, it will not let current through. Finally, if there is nothing at Pin 15, it will remain open not letting current through
The first 2 thoughts working for me, meaning when the pin is high, it allows current through and vice versa. However, when there is nothing in Pin 15, it seems to remain high. I've even tried to force it low then remove connection from Pin 15 to see if it blocks current, yet it allows current through
Any thoughts?
Thanks in advance,
Matt
