NPS1000UPZ

Overview

The NPS1000UPZ is a low-voltage, single-channel load switch from Nexperia designed for power distribution applications. It features a typical on-resistance of 11mΩ at 25°C to minimize voltage drop and power loss. The device supports an operating voltage range of 0.5V to 1.0V and handles up to 0.6A RMS current with a 1.5A peak capability. It includes controlled turn-on time, short-circuit tolerance up to 4.5A, and thermal shutdown protection. The component operates within a junction temperature range of -40°C to +105°C and is housed in a WLCSP-8 package.

Feature Summary

• Low on-resistance reduces IR voltage drop and power dissipation
• Controlled surge current charging for output capacitors during enable
• Internal discharge resistor prevents floating outputs when disabled
• Thermal shutdown with latch-off and input UVLO protection

Applications

• Mobile phones
• Wearable devices
• IoT modules

Procurement Notes

Verify the specific suffix UPZ corresponds to the WLCSP-8 packaging configuration as documented in official Nexperia datasheets. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure design compatibility with the specified 0.5V to 1.0V supply range and logic level requirements before integration.

Selection Notes

Select this component for space-constrained designs requiring efficient power management in low-voltage systems. The WLCSP-8 package offers a small footprint suitable for dense PCB layouts. Consider the 11mΩ on-resistance for applications prioritizing minimal power loss. Verify that the 1.5A peak current rating meets the transient load requirements of the target circuit.
