Overcurrent and short-circuit protections

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

circuit conditions (short-circuit to ground, short-circuit to VS and short-circuit 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 sizing properly the external

network connected to the EN\FAULT pin (refer to Figure 9).
