Fairchild Load Switches Offer Low Quiescent Current (1µA); Extend Battery Life In Biometric Sensor Modules
Fairchild Semiconductor states that it is bringing designers of biometric sensor modules advanced load switches with what is described as the industry’s lowest quiescent current. The FPF2024, FPF2025, FPF2026 and FPF2027 are IntelliMAX advanced load switches that are said to minimize the quiescent current and prolong battery life.
With a quiescent current of only 1µA, these advanced load switches use less than 2% of the current of alternate solutions whose quiescent current ranges from 60 to 80µA. 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 (1.6 to 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 advanced load switches address the space and ESD protection concerns facing portable designs.
The FPF2024, FPF2025, FPF2026 and FPF2027 utilize 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.
The units are priced (each, 1000 pcs.) at US $ 1.49, with a delivery of 12 weeks ARO.
