Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary by distributor. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required electrical parameters for your specific circuit design. Cross-reference datasheet revisions to confirm pinout and functional consistency.

Selection Notes

Select this component for applications requiring a single high-side switch with 1.5 A capability. It is suitable for systems operating between 0.9 V and 3.6 V. Consider the 140 mΩ on-resistance for power loss calculations. Verify that the logic control levels are compatible with your system's microcontroller or interface signals. Evaluate the thermal performance based on the expected load current and ambient temperature.

Part Context

This part belongs to NXP's general load switch portfolio, which includes small and tiny-package solutions supporting input voltages from 0.8 V to 5.5 V. It complements other devices like the NX5P2924 and NX3P2902BUK for various point-of-load power designs. The series is designed for efficiency and compactness in modern electronic systems.

Replacement Considerations

Check for direct substitutes within the NX3P series or equivalent high-side switches from other manufacturers. Ensure replacement parts match the 1.5 A current rating, 140 mΩ resistance, and 900 mV to 3.6 V supply range. Verify package compatibility and pinout alignment before substitution.
