For contrast, the oscillogram of a ‘hard’ shutdown is shown in Figure 9. The same IGBT, IRG4BC40KD,
and the same PCB pattern were used as in the example shown in Figure 8. The top trace is the IGBT
short circuit current and the bottom trace is the IGBT V

In summary, the IR2137, a monolithic IC, provides excellent protection and soft shutdown features in
an extremely compact and cost-effective package.
