Load switches minimise quiescent current

With a quiescent current of 1uA, the load switches use less than two per cent of the current of alternate solutions whose quiescent current ranges from 60-80uA.

They also provide robust current limiting protection that prevents damage from adverse events associated with unexpected current surges.

The FPF202x series features a wide operating range (1.6V-5.5V) to address the voltage specifications for biometric sensor modules found in laptops, ultra-mobile portable computers (UMPCs), smart phones and other portables.

Packaged in compact 1 x 1.5 WL-CSP packaging and bolstered with robust ESD protection (5.5kV), these load switches address the space and ESD protection concerns facing portable designs.

The FPF202x series is part of Fairchild's portfolio of Intellimax switches.

These load switches combine protection, control and fault monitoring functions in compact packaging to reduce complexity in power management designs and accelerate time to market.

The FPF2024, FPF2025, FPF2026 and FPF2027 utilise lead-free (Pb-free) terminals and have been characterised for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020.
