Current is used as an internal reference to declare a coil short condition when the output current is 0.5A higher
than the max current setting.

current will change when supply voltage and/or coil temperature changes.
In this example, the output PWM duty cycle
(0-100%) matches the percent of demand.
The output current will change when supply
voltage and/or coil temperature changes.
The evc/epc does not declare an error
because the output current 1.16A is not
0.5A higher than the max setting 0.7A.
In this example, the evc/epc declared an
error because the output current 1.16A is
0.5A higher than the max setting 0.63A.
