NCP338FCCT2G

Overview

The NCP338FCCT2G is a power distribution switch manufactured by onsemi, designed for load driver applications. It features a P-Channel output configuration housed in a compact 6-WLCSP package with dimensions of 0.8x1.2 mm. The device supports an input voltage range up to 5.5V and delivers a continuous current of 2A. Key electrical characteristics include a maximum on-resistance of 420 mΩ and a typical turn-on time of 116 µs. It operates within a temperature range of -40°C to +125°C and includes integrated load discharge capabilities.

Feature Summary

• Integrates P-Channel MOSFET technology for efficient power switching
• Features controlled slew rate to minimize inrush current and EMI
• Includes active load discharge path for rapid output capacitor discharge
• Utilizes ultra-small WLCSP packaging for space-constrained designs

Applications

• Portable electronic devices requiring compact power management
• Battery-powered systems needing efficient load switching
• Consumer electronics utilizing low-voltage power distribution
• Mobile communication equipment with strict size constraints

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'CCT2G' matches your board assembly requirements. Check for recent Product Change Notifications (PCN) regarding manufacturing site or material updates. Ensure compatibility with your PCB footprint design for the 6-WLCSP package. Validate operating temperature ranges against your final system environment specifications.

Selection Notes

Select this component when a small form factor and high current density are required. The P-Channel topology simplifies high-side switching control without level shifters. Consider the 420 mΩ on-resistance for thermal management calculations. The integrated discharge feature eliminates external components for safe power-down sequences. Evaluate the 116 µs turn-on time against system startup timing requirements.

Part Context

This part belongs to onsemi's NCP33x series of power switches, which focus on ultra-small footprints and high efficiency. The series targets portable applications where board space is limited. Similar parts in the family may offer different current ratings or pin configurations. The WLCSP package type is common in modern mobile and wearable electronics for minimal profile.

Replacement Considerations

Direct substitutes include other onsemi NCP33x series parts with compatible pinouts and electrical ratings. Verify that alternative P-Channel switches meet the 2A current and 5.5V voltage requirements. Ensure replacement packages match the 6-WLCSP dimensions for mechanical fit.
