The IRSF3031 is a three-terminal monolithic Smart Power
MOSFET with built-in short circuit, over-temperature, ESD and
over-voltage protections and dual set/reset input threshold .
The on-chip protection circuit latches off the Power MOSFET
in case the drain current exceeds 4A (typical) or the junction
temperature exceeds 165 o C (typical) and keeps it off until the
input is driven below the Reset Threshold voltage.
The drain to source voltage is actively clamped at 55V prior to
the avalanche of the Power MOSFET, thus improving its perfor-
mance during turn-off with inductive loads.
The input requirements are very low (100μA typical) which
makes the IRSF3031 compatible with most existing designs
based on standard power MOSFETs.
