recopy output delivers current only during ON time of the
output switch without overshoot (aperiodic settling).
precision can be improved significantly. One calibration point
at 25 °C for 50% of FSR allows removing part to part
contribution. So, the calibrated part precision goes down to 
+/-6.0% over [20% - 75%] output current FSR, over voltage
range (10 V to 16 V) and temperature range (-40 to 125 °C).

the corresponding output voltage is closed to half of battery.
This bit allows synchronizing current sense and diagnosing
short-circuit between OUT and VBAT terminals.
