Hey,
I'm starting on my summer project. I want to make a charging dock for my iPad with LED battery status indicator (Green - Charged, and Red - Charging).
I want to use a current comparator. So... iPad pulls high current when charging (red LED) and pulls low current when charged (green LED)
Can anyone recommend what should I use for the circuit? (cheap prices are always welcome).
Currently, I'm using the MCP6546 chip in multisim but I can't get the right current.
Source is 5V, 2 Amp... but so far my circuit can only provide uA and mV....
