Below we provide information about adding a circuitry to protect the L6203 DMOS Full Bridge Driver from Short Circuit. L6203 is a full bridge driver which combines isolated DMOS power transistors with CMOS and Bipolar circuits on the same chip and it is easy for the L6203 IC to have such shorts circuits since it is used as driver that often interfacing external circuit by means of wires.
In its application note, it is stated that there are three types of short circuit regarding this L6203: output to output short circuit, output to supply voltage short circuit, and output to ground short circuit. The figure above shows you a complete added short circuit protection schematic diagram of L6203 (click to enlarge).
Added circuitry schematic diagram for output to output short circuit or output to supply short circuit can also be found.
