The highly integrated miniPROFET (for fully PPRROOtected FFEETT) switch incorporates a broad range of
smart functions that make miniPROFETs ideal for the widest variety of automotive and industrial applications. miniPROFETS
are designed to be controlled directly from a single µC output pin. With a typical quiescent current of less than 10 µA , they
are positioned as the high-side switches of choice for battery-powered systems. Their built-in safety features protect both
the device and the application.
COMPACT DESIGN
As miniPROFETs require less
components than discrete
solutions, they enable more
compact, robust application
design. This reduces board
space and costs. The tightly
integrated design also reduces
wiring and connector require-
ments.

INTRODUCING ONE OF THE
Relay
APPLICATIONS
miniPROFETs are suited to automotive applications such as gen-
eral body control modules, instrument clusters, dashboard lighting and motor cotrols.
Industrial applications include relay and fuse replacement, lamps, solenoids, DC motors,
power control in appliances and portable tools, various automated designs in robotics,
and industrial control.
LOW QUIESCENT CURRENT SPARES BATTERIES
This latest generation ofsmall, intelligent, high-side power
switches features new low power ratings to significantly prolong battery life. Low current
consumption in the on state combined with a typical current consumpion of 10 µA in the
off state mate miniPROFETs ideal for battery powered applications.
BENEFITS OF REPLACING RELAYS WITH miniPROFETs
■More robust, reliable design
Insensitivity to mechanical movements
Integrated protective and diagnostic functions
Low drive power
Pulse Width Modulation (PWM) capabilities
Less noise and electromagnetic emission
No lifetime degradation
■Reduced system costs
Reduced board assembly costs
Low weight and installed volume
No restrictions on mounting position
No external circuitry for protection and diagnostics
SHORT CIRCUIT PROTECTION
The most important protective function of a miniPROFET is to
safeguard the application from destruction in the event of a short circuit. This is achieved
through a combination of both current limitation and thermal shutdown in the event of
excess temperature. By combining switching and protective functions in a single de-
vice, miniPROFETs eliminate the need for fuses, thus presenting a more cost effective and
robust alternative to standard relay and fuse solutions.

ALLROUND PROTECTION
miniPROFET intelligent power switchescontain a DMOS
power transistor plus CMOS logic circuitr y for complete, built-in protection. This new
family offers full protection against overloads, overvoltages, shor t circuits, excess
temperatures, loss of ground, loss of power supply and electrostatic discharge.
miniPROFET switches also include protection against dynamic overvoltages such
as load dump, and inductive load turn-off without the need for any additional
components.
