NCP458RFCCT2G

Overview

The NCP458RFCCT2G is a single load switch IC manufactured by onsemi, designed for power distribution applications. It supports a continuous current of 3A and features an active-high enable input. The device utilizes a CSP6 package with dimensions of 0.85mm x 1.25mm. It operates within an input voltage range of 0.75V to 5.5V. The component is classified as obsolete and has been discontinued.

Feature Summary

• Single load switch configuration for dedicated power rail management
• High current capability supporting up to 3A continuous load
• Compact footprint utilizing small outline packaging for space-constrained designs

Applications

• Power distribution in portable electronic devices
• Battery-powered equipment requiring efficient load switching
• General purpose power management circuits

Procurement Notes

This component is officially listed as obsolete and discontinued by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verification of part authenticity and condition is critical when sourcing from non-primary distributors. Factory orders are no longer accepted. Engineers should review the end-of-life notification documents provided by onsemi to confirm final shipment dates and transition recommendations before initiating procurement processes.

Selection Notes

Designers requiring this specific 3A single load switch must account for its discontinued status. Alternative solutions within the NCP45x family or newer generations should be evaluated for compatibility. Considerations include matching the required current rating, voltage range, and package dimensions. Verify that substitute components meet the same electrical specifications and thermal requirements to ensure system reliability without redesigning the entire power architecture.

Part Context

The NCP458RFCCT2G belongs to the NCP45x series of low voltage load switches. This series focuses on optimizing battery life in portable devices through low leakage and high efficiency. The specific model provides a single channel solution, distinguishing it from dual-channel variants in the same product line. It addresses the need for precise power control in compact mobile and wireless applications.

Replacement Considerations

NCP458R: Same functional type but different package suffix; verify pinout compatibility. NCP456R: Lower current rating (2A); suitable only if load requirements permit reduction.
