PROFET ™: Smart High-Side Switches
The highly integrated PROFET™ family (PROtected FET)
incorporates a broad range of smart features, like diagnosis
and protection. PROFET™ intelligent power switches
consist of DMOS power transistor and CMOS logic circuitry
for complete built-in protection.
The PROFET™ family oers protection against overload,
overvoltage, short-circuit, excessive temperature, ground
loss, power supply loss and Electrostatic Discharge
(ESD). The PROFET™ family products are also capable
of protecting against dynamic overvoltage such as load
dump and inductive load turn-o. For the benefits and
the functionality of the protection features, please refer to
www.infineon.com/profet.
The PROFET™ diagnostics oer the choice of either status
or current sense features, or a combination of both. In
the event of a malfunction, the status feature is able to
diagnose overtemperature or open-load. The PROFET™
diagnostic features also provide the user with precise
information about switch and load. Diagnostic feedback
and load current sensing minimize risks by eliminating the
need for additional discrete circuitry and assembly.
This vast range of smart features makes the PROFET™ ideal
for a variety of automotive (12V), trucks & agriculture (24V)
and industrial applications.
