Overcurrent and short-circuit protections

The device embeds circuitry protecting each power output against the overload and short-

circuit conditions (short to ground, short to VS and short between outputs).

When the overcurrent or the short-circuit protection is triggered, the power stage is disabled

and the EN\FAULT input is forced low through the integrated open drain MOSFET

The power stage is kept disabled and the open drain MOSFET is kept ON until the

Figure 8. Overcurrent and short-circuit protections management

The total disable time after an overcurrent event can be set by properly sizing the external

network connected to the EN\FAULT pin (refer to Figure 9 and Figure 10):
