NLPS22990MN1TAG

Overview

The NLPS22990MN1TAG is a single-channel high-side power distribution switch manufactured by onsemi. It operates within an input voltage range of 600 mV to 5.5 V and supports a maximum continuous output current of 10 A. The device features a typical on-resistance of 3.9 mΩ, with a maximum specified at 6 mΩ. Key timing parameters include a maximum turn-on time of 24 μs and a maximum turn-off time of 6 μs. It is housed in a WDFN-10 package and is rated for operation between -40°C and +105°C.

Feature Summary

• Integrates a programmable rise time function via an external capacitor to control inrush current during startup.
• Includes a Power Good (PG) open-drain indicator that signals when the switch is fully conducting and stable.
• Utilizes an N-channel MOSFET architecture to minimize conduction losses and voltage drop across the load.

Applications

• Power distribution in automotive infotainment and body control modules
• Industrial equipment requiring robust high-side switching
• Portable devices needing efficient battery-powered load management

Procurement Notes

Verify the complete part number including suffixes against official onsemi documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the WDFN-10 footprint matches your PCB design guidelines. Cross-reference thermal performance data with your system's heat dissipation requirements before finalizing procurement decisions.

Selection Notes

Select this component when a high-current single-channel switch with precise inrush control is required. The integrated Power Good feature simplifies system monitoring compared to basic switches. Ensure the application voltage remains within the 0.6 V to 5.5 V range and that the thermal design accommodates the power dissipation associated with the 10 A continuous current rating.

Part Context

This part belongs to onsemi's NLPS series of power distribution switches. These components are designed for general-purpose high-side switching applications where reliability and efficiency are critical. The series typically offers various current ratings and package options to suit different board space and power constraints.

Replacement Considerations

Consult onsemi's official cross-reference tools or distributor databases for verified equivalent parts. Ensure any substitute maintains compatible voltage, current, and package specifications.

FAQ

How is the rise time controlled?

The rise time is adjusted by connecting an external capacitor to the CT pin. The duration depends on the capacitance value and the input voltage.

What does the Power Good signal indicate?

The PG signal indicates that the internal FET gate is fully raised and the on-resistance has reached its final low value, confirming the load is ready for full current.
