The above figure shows the MC33341 configured for load low−side current sensing with an externally adjustable voltage and current
threshold. Operation of this circuit is similar to that of Figure 20. The respective voltage and current regulation threshold can be adjusted
over a range of 0 to 1.2 V and 0 V to 200 mV, with respect to Pin 4.
