CMOS load switches for home electronics and diagnostic metering apps

Fairchild Semiconductor has introduced the FPF110x, a new series of IntelliMAX slew-rate load switches that addresses the need for low power consumption and robust protection for home and diagnostic metering applications such as portable medical devices, Smart phones, digital cameras, GPS and Navigation Equipment, notebooks and Mobile devices.

The FPF110x features high performance includes over 30 percent reduction in RDS (ON), integrated analog switch control functionality and operation from 1.2 to 4V allowing direct load switch interconnection into microprocessors for software-transparent operations.

Based on power CMOS silicon, the FPF110x series eliminates the need for additional input capacitors, and offers robust protection through integrated slew rate control. Slew rate options of 65µs and 130µs are ideal to meet individual customer needs and provide system stability over the entire operating range to avoid voltage sags and current spikes. Additionally, ESD protection of 4kV reduces failures during manufacturing and the false readings caused by adverse ESD events.

The FPF1104 and FPF1108 load switches offer an additional integrated NMOS device for load discharge of output capacitance in off-state cycles.
