Timing Diagrams
In case of a severe fault (for example sudden short-circuit of
the output load) the SENSE pin exceeds the V
and GATE immediately pulls down until the Active Current
Limit loop establishes control of the current in the MOSFET.

Careful selection of TIMER capacitor and MOSFET with
adequate current and voltage ratings will prevent damage to
MOSFET low impedance faults.
