Overview
The NCP337FCT2G is a high-side power switch IC from onsemi, designed for load distribution applications. It features an integrated P-channel MOSFET capable of handling up to 2A output current with a maximum on-resistance of 420 milliohms. The device operates within a supply voltage range of 1.2V to 5.5V and supports a maximum operating temperature of +125°C. Packaged in a compact 4-WLCSP (0.96x0.96mm) format, it includes controlled slew rate and load discharge capabilities.
Feature Summary
- Integrates a high-side P-channel power switch for efficient load distribution
- Provides automatic load discharge path to rapidly remove stored energy
- Features controlled slew rate to minimize inrush current during turn-on
Applications
- Portable electronic devices requiring compact power management
- Battery-powered systems needing efficient load switching
- General-purpose load distribution in consumer electronics
Procurement Notes
Verify the specific suffix 'FCT2G' against the official onsemi datasheet to confirm package dimensions and tape/reel specifications. Ensure the component meets RoHS compliance requirements as indicated in the manufacturer's material declaration. Cross-reference the ordering information with the latest product change notices to avoid discrepancies in packaging or bump site transfers.
Selection Notes
Select this component when a small footprint and high current capability are required for high-side switching. The 420 milliohm resistance offers a balance between conduction loss and package size. Consider the 1.2V minimum operating voltage for compatibility with low-voltage logic interfaces. The WLCSP package is suitable for space-constrained PCB layouts where traditional SOIC packages are too large.
Part Context
The NCP337 belongs to the NCP33x series of ultra-small load switches from onsemi. This family provides integrated protection and control features in minimal packaging. The NCP337 specifically addresses applications requiring robust load switching with automatic discharge, distinguishing it from basic switches that lack these protective functions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference data through official distributor channels before substitution.
