7.0 Output short circuit test
7.1 Apply a short at one of the outputs. The short can be
applied electronically using a MOSFET connected
between Vout and Gnd or simply by connecting Vout
to Gnd. Monitor the voltage across the MOSFETs
[V(D1) – V(D2)] with differential probe if available.
Then measure the response time between when
[V(D1) – V(D2)] reaches the forward overcurrent
threshold (114 mV) and when the MOSFETs are
disconnected (or turned off). An example for PI2002
response time to an output short circuit is shown in
Figure 6.
