NPS1001UPZ

Overview

The Nexperia NPS1001UPZ is a single-channel load switch IC designed for power distribution applications. It operates within a supply voltage range of 500 mV to 1.8 V and supports an output current of 1.5 A with a current limit of 4.5 A. The device features a maximum on-resistance (RDSon) of 18 mΩ, ensuring minimal voltage drop and power loss. It includes controlled turn-on time (212 µs max) and turn-off discharge resistance (8 Ω). The component functions reliably across a temperature range of -40°C to +105°C and is housed in a WLCSP-8 package.

Feature Summary

• Low on-resistance minimizes IR voltage drop and power dissipation during operation.
• Integrated controlled surge current management charges output capacitors safely upon enablement.
• Internal discharge resistor prevents floating outputs when the switch is disabled.
• Logic-compatible enable input simplifies control interface integration.

Applications

• Mobile phone power management
• Wearable electronic devices
• Portable consumer electronics

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official documentation to confirm compliance status and packaging details. Ensure the WLCSP-8 footprint matches the design layout. Confirm availability through authorized channels as distribution may be restricted in certain regions. Cross-reference the RoHS declaration with the latest datasheet revision to ensure regulatory adherence for the target market.

Selection Notes

Select this component for low-voltage systems requiring efficient power switching with minimal footprint. The 1.5 A continuous current rating suits moderate load requirements. Verify that the 1.8 V maximum supply voltage aligns with the system's power rail. The WLCSP-8 package is ideal for space-constrained designs where board area is limited compared to traditional surface-mount packages.

Part Context

This part belongs to the Nexperia NPS100x series of low-voltage load switches. The series is characterized by ultra-small form factors and high efficiency. The NPS1001 variant specifically offers higher current capabilities compared to lower-rated siblings like the NPS1000. It is engineered for portable applications demanding reliable power distribution in compact enclosures.

Replacement Considerations

Nexperia NPS1000UPZ is a related series member with similar functionality but different current ratings. Verify electrical parameters such as RMS current and RDSon before substitution. Ensure pin compatibility and thermal performance meet the application requirements.
