power management product selection guide - International Rectifier

Automotive Intelligent Power Switch | PRODUCT FAMILIES
The IR Advantage
• Most rugged, efficient and compact
switches for the harshest environments.
• Provides charge pump and full switch
protection with no additional circuitry.
• Up to 30% smaller PCB area than a
discrete charge pump circuit.
• More than 1000 times longer life than
electro-mechanical relays due to self
protection and absence of wear and tear.
• Up to 20% lower on-resistance than
relays reduces heat dissipation and
heat sinks.

Ultra-Low R DS(on) Self-Protected Intelligent Power Switches
Intelligent Power Switches (IPS) from International Rectifier integrate a low RDS(on) output
HEXFET ® power MOSFET into a single package with protection and control circuits, making
them the most rugged, efficient and compact devices available for automotive loads in harsh
environments. All devices are qualified to AEC Q100 Qualification standard and devices with
“PbF” suffix are RoHs compliant according to the European Union RoHs Directive.
Built-in protection features, like over-temperature, over-current and active inductive energy
clamp protect against short circuits, stalled motors and excessive ambient temperature.
Designed to safely handle ordinary overload conditions as well as several extraordinary
conditions, including loss of ground, load dump and reverse battery, IPS devices eliminate
switch failures with the best efficiency and no addition in part count. Over-design for low
occurrence fault situations are minimized. The embedded charge pump makes the interface
to the micro-controller very simple with full logic-level compatibility.
The double level shifter circuitry that drives the MOSFET in the High-Side Switch (HSS) family
provides immunity from large offsets between the logic ground and the load ground and
short switching times. Internal slew rate control for turn-on/off and the use of a low noise
charge pump means lower EMI, with ground noise generation of less than 10mA.
