NCP435FCT2G

Overview

The NCP435FCT2G is a high-side load switch from onsemi, housed in a 4-pin WLCSP package measuring 0.96 x 0.96 x 0.33 mm. It supports an input voltage range of 1.2 V to 5.5 V and delivers a maximum output current of 2 A. The device features a typical on-resistance of 65 mΩ and a maximum on-resistance of 420 mΩ. Operating temperatures span from -40 °C to +125 °C, with a maximum turn-on time of 116 µs.

Feature Summary

• Ultra-small footprint utilizing a 4-pin WLCSP package for space-constrained designs.
• Integrated load discharge functionality to rapidly remove charge from downstream capacitors.
• High current capability supporting up to 2 A output for efficient power distribution.

Applications

• Portable consumer electronics requiring minimal board space
• Battery-powered devices needing efficient power management
• Embedded systems with strict thermal and size constraints

Procurement Notes

Verify the specific suffix 'FCT2G' against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the procurement channel provides original component traceability. Cross-reference the RoHS compliance status directly with the official documentation prior to integration into production lines.

Selection Notes

Select this component when a compact form factor is critical alongside moderate current handling. The low on-resistance minimizes power loss during conduction. Consider the wide operating temperature range for harsh environments. Evaluate the turn-on speed requirements against system timing constraints before finalizing the design choice.
