Never power the device without keeping RSTIN pin grounded: the device could enter in
unpredictable states, risking also permanent damages.
Warning:

and
It is recommended to provide the external hardware with a
current limitation circuitry. This is necessary to avoid
permanent damages of the device during the power-on
transient, when the capacitance on V
the on-chip voltage regulator functionality 10nF are
sufficient: anyway, a maximum of 100nF on V
not generate problems of over-current (higher value is
allowed if current is limited by the external hardware).
External current limitation is anyway recommended also to
avoid risks of damage in case of temporary short between
V
currents of several tens of Ampere, so the current shall be
limited by the external hardware. The limit of current is
imposed by power dissipation considerations (Refer to
Electrical Characteristics Section).
