New load switches from Fairchild Semiconductor for mid-voltage apps

Fairchild Semiconductor has released the AccuPower load switch series, 2.8V to 36V integrated load switches designed to address the designer's mid-voltage needs. AccuPower load switch series include the FPF2700, FPF2701 and FPF2702. These current limiting load switches feature built-in protection that can protect the system from large current conditions.These devices also feature a slew rate controlled N-Channel MOSFET which limits the amount of in-rush current and protects the system from abnormalities on the main power supply rails.

The AccuPower load switches operate from input voltage range of 2.8V to 36V. These devices offer low RDS(ON) of 90mohms (typical) and feature Safe Operation Area (SOA) current limit protection. They are suggested for motor drives, portable power, digital cameras, industrial and computing applications.

The AccuPower load switch series also feature under-voltage lock-out (UVLO) protection and thermal shutdown protection. Switch control is completed by a logic input (ON) capable of interfacing directly with the low voltage control signal. When the switch current reaches the current limit, the device operates in a constant-current mode to prohibit excessive currents from causing damage.
