* Switch off 10ohm shunt resistor with integrated fast comparator interrupt, when current exceeds 5mA range. Faster response to over-range, avoid significant voltage drop due to 10ohm shunt resistor

* Switch off MOSFET and latched when over-current detected with integrated fast comparator. Threshold defined by a resistor voltage divider. However usable current range reduced to less than 500mA due to relatively high gain 64.9. Will be changed to 59 as with 5mA range to allow current higher than 500mA in next version.
