NCP335FCT2G

Overview

The NCP335FCT2G is a single-channel load switch IC manufactured by onsemi, designed for power distribution applications. It features a P-channel MOSFET capable of delivering up to 2A output current with a maximum on-resistance of 420 mOhms. The device operates within a supply voltage range of 1.2V to 5.5V and supports an input-to-output ratio of 1:1. Key electrical parameters include a maximum run time of 116 us and a power dissipation rating of 500 mW. It functions reliably across an operating temperature range from -40°C to +125°C TJ.

Feature Summary

• Integrates an ultra-small form factor load switch with auto-discharge functionality for rapid load release.
• Features controlled slew rate capability to minimize inrush current during turn-on events.
• Utilizes a compact 4-WLCSP package (0.96x0.96 mm) optimized for space-constrained surface mount designs.

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing low quiescent current solutions
• Consumer electronics utilizing high-side switching architectures

Procurement Notes

Verify the specific suffix 'FCT2G' against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the WLCSP-4 footprint dimensions carefully during PCB layout to prevent soldering defects. Confirm that the 2A continuous current rating aligns with your system's peak load requirements without exceeding thermal limits.

Selection Notes

Select this component when a compact, high-current load switch is needed for voltages between 1.2V and 5.5V. The 420 mOhms on-resistance offers a balance between conduction loss and cost. Consider the 116 us run time for timing-sensitive enable signals. The wide temperature range makes it suitable for industrial or automotive environments where extreme conditions are expected. Compare against NCP333 variants if lower current is sufficient.
