I am in need of sensing the current in a circuit and cutting off power when current exceeds a threshold which should be about 2A. It seems that everything I've read recommends using separate "current sense amplifier" and "voltage comparator" packages but I would think that this need is so common that someone would manufacture a device that does both in the same package. Board space is limited and I don't need to access the intermediate analog signal between the two devices. I have already tried using just a voltage comparator but it doesn't seem to be sensitive enough by itself to detect the small voltage difference across the current sense resistor.
The device needs to operate with a 12VDC supply. I am setting absolute max voltage to about 13.5VDC so the device should be rated for more than 15VDC.
