family (PROtected FET)
incorporates a broad range of smart features. PROFET intelligent power
switches consist of a DMOS power transistor and CMOS logic circuitry for
complete built-in protection.
T H E P R O F E T F A M I L Y offers protection against: overload,
overvoltages, short circuits, excess temperature, ground loss, power supply
loss and electrostatic discharge. The PROFET family products are also
capable of protecting against dynamic overvoltage such as load dump and
inductive load turn-off. For the benefits and the functionality of the protection
features, please refer to details in the datasheets (www.infineon.com / profet).
T H E P R O F E T D I A G N O S T I C S offer 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 costs by eliminating the need for additional discrete
circuitry and assembly.
T H I S V A S T R A N G E of smart features makes the PROFET ideal
for a variety of automotive and industrial applications, e.g:
Automotive Lighting
HVAC
24 V Applications
Solenoid
Solid State Relay
Battery Management
