NX5P2190UKZ

Overview

The NX5P2190UKZ is a logic-controlled high-side power switch designed for 3 V to 5.5 V applications. It features an integrated P-channel MOSFET capable of handling up to 2 A continuous current with a maximum on-resistance of 100 mΩ at 4.0 V. The device includes adjustable current limiting via the ILIM pin, soft-start functionality, and comprehensive protection circuits such as over-temperature, over-voltage lockout, under-voltage lockout, reverse bias, and surge current protection. An open-drain fault output signals errors, while the enable input supports low-power mode operation.

Feature Summary

Integrated adjustable current limiting and soft-start control
Comprehensive protection against over-current, over-temperature, and reverse bias
Low-power mode with typical ground current of 20 μA
Compatible with low-voltage control logic

Applications

USB OTG applications
Consumer electronics
Power adapters and chargers

Procurement Notes

Verify component authenticity through authorized NXP distributors or direct channels. Confirm package integrity and marking accuracy upon receipt. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions. Ensure storage and handling comply with moisture sensitivity level requirements specified in the manufacturing data sheet.

Selection Notes

Select this component for designs requiring precise current management and robust fault protection in 3 V to 5.5 V systems. The adjustable ILIM pin allows customization of over-current thresholds. Consider the 100 mΩ on-resistance for efficiency calculations. Verify compatibility with system voltage levels and thermal requirements before integration into the final product design.
