NCP456RFCCT2G

Overview

The NCP456RFCCT2G is a single load switch IC manufactured by onsemi, designed for power distribution in low voltage rail applications. It features an NMOSFET structure with an extremely low on-resistance (Ron) of 24mΩ to optimize current consumption and reduce leakage current. The device supports a wide input voltage range from 0.75V to 5.5V and provides a maximum DC output current of 2A. It includes reverse voltage protection to eliminate leakage from OUT to IN when Vout exceeds Vin. The component is housed in a compact CSP6 package measuring 0.85mm x 1.25mm.

Feature Summary

• Extremely low on-resistance NMOSFET structure minimizes conduction loss and improves power efficiency.
• Wide operating voltage range accommodates various power supply requirements from 0.75V to 5.5V.
• Integrated reverse blocking control circuit prevents backflow leakage current for enhanced system reliability.
• Compact CSP6 package design saves significant PCB space for portable and miniaturized devices.

Applications

• Power management for laptops and tablets
• Battery-powered wireless communication devices
• Mobile phone power rail switching
• Digital camera power distribution

Procurement Notes

Verify the exact ordering suffix and package variant against the manufacturer's latest datasheet before procurement. Confirm that the CSP6 package dimensions align with your PCB footprint requirements. Check for any specific handling instructions related to the cut tape or reel packaging format provided by the distributor. Ensure compatibility with your target voltage levels within the specified 0.75V to 5.5V range.

Selection Notes

Select this component when designing circuits requiring high efficiency in low voltage environments. The 2A current capability suits moderate load switching needs. Consider the external logic control interface for enable functionality. The low leakage characteristics make it suitable for battery-operated systems where standby power conservation is critical. Evaluate the small form factor against available board space constraints.
