Fairchild Debuts FPF200X Series of IntelliMAX Load Switches

Fairchild Semiconductor International Inc. (South Portland, ME) announced its new FPF200X Series of IntelliMAX™ integrated, low-power, load switches targeting portable battery-powered applications. The IntelliMAX devices are suitable for cell phone handsets, MP3 players, digital still cameras, notebook computers, networking products and PDAs. In addition, they are well suited for low-voltage, in-rush, current control in telecom/industrial equipment.

The FPF200X devices' wide input-voltage range of 1.8 to 5.5 V is suitable for electronics with battery-operating voltages that can dip as low as 1.8 V. Each IntelliMAX load switch replaces multiple active and passive components used in traditional analog IC control functions and MOSFET power switch approaches.

Each FPF200X load switch includes controlled switch turn-on, current-limiting with 50 mA or 100 mA options, under-voltage lockout and thermal shutdown. Also included are a flag for fault conditions with options for fault blanking; and auto-restart functions—all with 4 kV ESD protection. IntelliMAX also features low-shutdown current (<1 µA) to conserve battery life, and a fast current-limit response time (3 µs for nominal over-current conditions, 20 ns for hard short conditions) for safety/fault protection.

The products are lead-free and meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B, and are compliant with the European Union requirements. Prices for the FPF2000 though the FPF2007 are $0.57 for 1,000-piece quantities. Available now, delivery is four weeks ARO.
