Load Management Switch offers tight current limit tolerance.
July 21, 2009 -
Packaged in dual configuration, IntelliMAX(TM) FPF23xx series offers tight tolerance (15%) current limit protection that lets designers reduce max operating threshold. This facilitates component sizing and application evaluation while not interfering with normal operating performance of design. With less than 3 µA leakage current draw and less than 20 µsec protection response, switches are suited for providing current-limiting protection in STB, computing, and cell phone applications.

Fairchild Semiconductor's IntelliMAX(TM) Dual Switches Offer the Industry's Tightest Current Limit Tolerance
Low Power Draw for Higher Efficiency in OFF Mode
SAN JOSE, Calif. - July 9, 2009- Fairchild Semiconductor (NYSE: FCS) brings designers of set-top boxes, notebooks, netbooks and ultra-mobile portable devices (UMPCs) a new family of advanced load switches, the FPF23xx series. Packaged in a dual configuration, these devices offer the industry's tightest tolerance (15 percent) current limit protection, simplify design and accelerate the time-to-market window. This tighter tolerance allows designers to reduce the maximum operating threshold (i.e., the upper current limit), which eases component sizing and application evaluation, while not interfering with the normal operating performance of the design.
This current limit protection design challenge can be seen in multiple-USB port power applications, where designers must protect their systems from excessive loads on the USB interface. USB 2.0, the current standard, specifies a maximum current of 500mA. Using Fairchild's IntelliMAX, advanced load switches, designers meet this specification by setting the device's minimum current limit to 500mA, which at 15 percent tolerance, equates to a maximum current limit of approximately 700mA. The equivalent performance using a 25 percent tolerance-device is 500mA minimum and 900mA maximum, or almost twice the set point. This performance, coupled with its low (<3uA) leakage current draw and an ultra-fast (<20us) protection response, make Fairchild's FPF23xx series ideal for providing current-limiting protection in set-top boxes, computing and cell phone applications.
The FPF2300, FPF2302, FPF2303, FPF2310, FPF2312 and FPF2313 are part of a comprehensive family of IntelliMAX advanced load management switches. These devices provide robust protection and power conditioning for a broad range of computing, consumer and portable applications. With their high-level of integration, these solutions are easy to design-in, save valuable PCB space and reduce overall component count.
