Description
The AUIPS1031(S)(R)PbF is a three terminal Intelligent
Power Switch (IPS) that features a low side MOSFET with
over-current, over-temperature, ESD protection and drain
to source active clamp. This device offers protections and
the high reliability required in harsh environments. The
switch provides efficient protection by turning OFF the
power MOSFET when the temperature exceeds 165°C or
when the drain current reaches 18A. The device restarts
once the input is cycled. A serial resistance connected to
the input provides the diagnostic. The avalanche capability
is significantly enhanced by the active clamp and covers
most inductive load demagnetizations.
