NCP380LSNAJAAT1G

Overview

The NCP380LSNAJAAT1G is a high-side power distribution switch featuring an integrated P-channel MOSFET with a maximum on-resistance of 95 mOhms. It supports a load voltage range of 2.5 V to 5.5 V and delivers up to 1 A output current. The device includes adjustable current limiting from 500 mA to 2.1 A via an external resistor. Key protection features include overcurrent protection, under-voltage lockout (UVLO), and reverse voltage detection. It operates within a temperature range of -40°C to +85°C and is housed in a TSOP-6 package.

Feature Summary

• Integrates a P-channel MOSFET for high-side switching applications
• Provides adjustable current limiting to protect against short circuits and overload conditions
• Includes controlled slew rate to minimize current ringing during switching events
• Features logic-controlled enable input and status flag output for fault indication

Applications

• Power distribution systems requiring high-side switching
• Applications involving large capacitive loads
• Systems susceptible to short-circuit conditions
• General-purpose load drivers with current protection needs

Procurement Notes

Verify the specific suffix 'A' and 'T1G' to ensure correct tape-and-reel packaging and RoHS compliance. Confirm that the TSOP-6 package matches your PCB footprint requirements. Check for any recent Product Change Notifications regarding wafer fab or material changes that may affect long-term supply chain stability.

Selection Notes

Select this component when a high-side switch with adjustable current limit is required. Ensure the external resistor value sets the current threshold within the 500 mA to 2.1 A range suitable for your load. Verify that the 2.5 V to 5.5 V operating voltage aligns with your system's power rails. Consider the thermal dissipation capabilities given the 95 mOhm resistance and package type.

Part Context

This part belongs to the NCP380 series of power distribution switches designed by onsemi. The series focuses on providing robust protection for loads in automotive and industrial environments. The LSNAJA variant specifically denotes the high-side configuration with adjustable current limits and standard packaging options available through major distributors.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the NCP380 family. Other variants may offer fixed current limits or different packages such as DFN. Ensure any substitute maintains the same voltage rating and current handling capabilities.
