Load switches offer precise power distribution

San Jose, Calif. — Fairchild Semiconductor has launched a series of advanced load switches with high current limiting accuracy for robust circuit protection. This tight tolerance FPF22xx series is said to provide an optimal design balance between ensuring sufficient system protection and delivering high performance.

The FPF22xx series' protection features include under-voltage lockout (UVLO), thermal shutdown and current limiting. Under-voltage lockout turns off the switch if the input voltage drops below an under-voltage lockout threshold, preventing circuit damage. Thermal shutdown averts any damage due to excessive heat and eliminates the need for external circuitry. Current limiting ensures that the current through the switch doesn't exceed a maximum value, while not limiting it to less than the value needed to deliver the right amount of current at the right time.

All of these features provide a robust protection interface between the application circuitry, battery and other accessories. With this strong protection and a wide operating range from 1.8 V to 5.5 V, these FPF22xx switches simplify design; reduce component count and minimize board space in cell phones, GPS navigation devices, notebook computers, glucometers and many other handheld applications, Fairchild said.

The IntelliMAX advanced load switches address a wide operating range (1.2 V to 20 V) and serve portable, low-voltage industrial, telecom and medical applications as well as other systems that require power load switching.

The FPF22xx series use lead-free (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 RoHS compliant.

Pricing: $1.19 in quantities of 1,000.
