Smallest load switches give 60% space savings

Fairchild Semiconductor Corp. has released the industry's smallest advanced load switches. The FPF218x and FPF219x series of IntelliMAX load switches in 1mm x 1.5mm wafer-level chip-scale packaging offer 60 percent space savings making them ideal for space-constrained portable applications. They retain the same low RDS(ON) performance found in standard leaded-package devices.

These two series of IntelliMAX products offer integrated protection circuitry, including over-current protection, current blanking, reverse-current blocking, over temperature and thermal shutdown protection. Included in this series is a new feature called "Power Good," which provides a logic source sense signal, and can be used to validate the presence of the power supply on the load switch's input pin. All of these built-in features provide robust protection from the harshest of mobile environments.

The FPF218x and FPF219x series utilize Pb-free terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).

The switches cost 78 and 84 cents each for the FPF218x series and the FPF219x series respectively, for orders of 1,000 pieces. Samples are available.
