SAN JOSE, Calif. -- July 24, 2012

High-complexity mobile devices, such as smart phones, tablets, digital cameras
and other consumer goods require seamless power management and battery
switching in order to provide greater flexibility and better reliability.
Fairchild Semiconductor’s (NYSE: FCS) IntelliMAX^TM family of advanced load
management switches help designers increase system protection and reduce
complexity in their designs while achieving greater system power and

With features such as slew rate control to prevent inrush currents,
over-current limit and thermal shutdown protection, reverse current blocking
and low operating input voltage, Fairchild’s comprehensive portfolio of
IntelliMAX smart load switches are capable of handling a wide range of
applications with multi-channel configurations and high-voltage and current
loads. The expansion of the IntelliMAX series addresses the dynamic power
challenges of light industrial applications with one-chip solutions that
provide designers off-the-shelf capability for their design needs, reduced
component counts and increased efficiency.

For smart devices and portable storage devices that require a high current
capability and low ON-resistance solution for power path management, the
FPF1039 and FPF1048 switches offer an ON-resistance of 20mΩ and 23mΩ, and an
input voltage range of 1.2V – 5.5V and 1.5V – 5.5V, demonstrating
exceptionally low shutdown current drain to help facilitate compliance in
low-standby power applications. The optimized slew rate controlled turn-on
characteristics with TR = 2.7mS prevents voltage droop on supply rails with
bulk capacitances as large as 200µF. The FPF1048 product also offers True
Reverse Current Block to avoid unwanted reverse power regardless of the device
being on or off.

Full-function load switches with adjustable current limits, such as the
FPF2165R and FPF2195, are well suited for applications with physical
connectors like USB and HDMI™ devices that may encounter large current
conditions. Input power budget control can be easily adjusted with a current
limit with an external resistor which offers reverse current blocking to
prevent unwanted reverse current when the device is turned off. The devices
operate in a constant-current mode to help protect against current damage and
maintain limited current after a current limit fault.

Suitable for wireless charging applications with a dual-input single-output
(DISO) load switch, the FPF1320 and FPF1321 devices perform seamless
power-source transitions between two input power rails using the SEL pin with
advanced break-before-make operation. These devices are designed to interface
directly with low-voltage control signal General Purpose Input Output (GIPO)
